.sp
\fBBuilding using make\fP
.sp
CMake will generate a Makefile and other configuration files for the build. As a rule of thumb, you should configure the
build \fIoutside of the source tree\fP in order to keep different configurations isolated. If you are unsure where to
execute the build, just use a temporary directory:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
cd $(mktemp \-d /tmp/cbor_build.XXXX)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Now, assuming you are in the directory where you want to build, build libcbor as a \fBstatic library\fP:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
cmake \-DCMAKE_BUILD_TYPE=Release path_to_libcbor_dir
make cbor
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
\&... or as a \fBdynamic library\fP:
.INDENT 0.0
.INDENT 3.5
.sp

.ft C
cmake \-DCMAKE_BUILD_TYPE=Release  \-DBUILD_SHARED_LIBS=ON path_to_libcbor_dir

To install locally:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
make install
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Root permissions are required on most systems when using the default installation prefix.
.sp
\fBPortability\fP
.sp
libcbor is highly portable and works on both little\- and big\-endian systems regardless of the operating system. After building
on an exotic platform, you might wish to verify the result by running the \fI\%test suite\fP\&. If you encounter any problems, please
report them to the \fI\%issue tracker\fP\&.
.sp
libcbor is known to successfully work on ARM Android devices. Cross\-compilation is possible with \fBarm\-linux\-gnueabi\-gcc\fP\&.
.SS Linking with libcbor
.sp
If you include and linker paths include the directories to which libcbor has been installed, compiling programs that uses libcbor requires
no extra considerations.
.sp
You can verify that everything has been set up properly by creating a file with the following contents
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
#include <cbor.h>
#include <stdio.h>

int main(int argc, char * argv[])
{
    printf(\(dqHello from libcbor %s\en\(dq, CBOR_VERSION);
}
.ft P
.fi
.UNINDENT

.sp
.nf
.ft C
cc hello_cbor.c \-lcbor \-o hello_cbor
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
libcbor also comes with \fI\%pkg\-config\fP support. If you install libcbor with a custom prefix, you can use pkg\-config to resolve the headers and objects:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
cc $(pkg\-config \-\-cflags libcbor) hello_cbor.c $(pkg\-config \-\-libs libcbor) \-o hello_cbor
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
\fBA note on linkage\fP
.sp
libcbor is primarily intended to be linked statically. The shared library versioning scheme generally follows \fI\%SemVer\fP, but is irregular for the 0.X.Y development branch for historical reasons. The following version identifiers are used as a part of the SONAME (Linux) or the dylib \fI\%\(dqCompatibility version\(dq\fP (OS X):
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.IP \(bu 2
0.Y for the 0.Y.Z branch. Patches are backwards compatible, minor releases are generally not and require re\-compilation of any dependent code.
.IP \(bu 2
X for the X.Y.Z stable versions starting 1.X.Y. All minor release of the major version are backwards compatible.

.sp
\fBWARNING:\fP

.SS Troubleshooting
.sp
\fBcbor.h not found\fP: The headers directory is probably not in your include path. First, verify the installation
location by checking the installation log. If you used make, it will look something like
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C

.UNINDENT
.UNINDENT
.sp
Make sure that \fBCMAKE_INSTALL_PREFIX\fP (if you provided it) was correct. Including the path path during compilation should suffice, e.g.:
.INDENT 0.0
.INDENT 3.5

.SS Usage & preliminaries
.SS Version information
.sp
libcbor exports its version using three self\-explanatory macros:
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.IP \(bu 2
\fBCBOR_MAJOR_VERSION\fP
.IP \(bu 2
\fBCBOR_MINOR_VERSION\fP

\fBCBOR_PATCH_VERSION\fP
.UNINDENT
.UNINDENT
.UNINDENT
.sp
The \fBCBOR_VERSION\fP is a string concatenating these three identifiers into one (e.g. \fB0.2.0\fP).
.sp
In order to simplify version comparisons, the version is also exported as
.INDENT 0.0
.INDENT 3.5

The single most important thing to keep in mind is: \fI\%cbor_item_t\fP \fBis an opaque type and should only be manipulated using the appropriate functions!\fP Think of it as an object.
.sp
The \fIlibcbor\fP API closely follows the semantics outlined by \fI\%CBOR standard\fP\&. This part of the documentation provides a short overview of the CBOR constructs, as well as a general introduction to the \fIlibcbor\fP API. Remaining reference can be found in the following files structured by data types.
.sp
The API is designed to allow both very tight control & flexibility and general convenience with sane defaults. [1] For example, client with very specific requirements (constrained environment, custom application protocol built on top of CBOR, etc.) may choose to take full control (and responsibility) of memory and data structures management by interacting directly with the decoder. Other clients might want to take control of specific aspects (streamed collections, hash maps storage), but leave other responsibilities to \fIlibcbor\fP\&. More general clients might prefer to be abstracted away from all aforementioned details and only be presented complete data structures.

.SS Memory management and reference counting
.sp
Due to the nature of its domain, \fIlibcbor\fP will need to work with heap memory. The stateless decoder and encoder doesn\(aqt allocate any memory.
.sp
If you have specific requirements, you should consider rolling your own driver for the stateless API.
.SS Using custom allocator
.sp
\fIlibcbor\fP gives you with the ability to provide your own implementations of \fBmalloc\fP, \fBrealloc\fP, and \fBfree\fP\&.
This can be useful if you are using a custom allocator throughout your application,

.SS Reference counting
.sp
As CBOR items may require complex cleanups at the end of their lifetime, there is a reference counting mechanism in place. This also enables a very simple GC when integrating \fIlibcbor\fP into a managed environment. Every item starts its life (by either explicit creation, or as a result of parsing) with reference count set to 1. When the refcount reaches zero, it will be destroyed.
.sp
Items containing nested items will be destroyed recursively \- the refcount of every nested item will be decreased by one.
.sp
The destruction is synchronous and renders any pointers to items with refcount zero invalid immediately after calling \fI\%cbor_decref()\fP\&.

.SS Streaming Encoding
.sp
\fI\%cbor/encoding.h\fP
exposes a low\-level encoding API to encode CBOR objects on the fly. Unlike
\fBcbor_serialize()\fP, these functions take logical values (integers, floats,
strings, etc.) instead of \fI\%cbor_item_t\fP\&. The client is responsible for
constructing the compound types correctly (e.g. terminating arrays).
.sp
Streaming encoding is typically used to create an streaming (indefinite length) CBOR \fI\%strings\fP, \fI\%byte strings\fP, \fI\%arrays\fP, and \fI\%maps\fP\&. Complete example: \fI\%examples/streaming_array.c\fP

Due to their largely similar semantics, the following functions can be used for both Type 0 and Type 1 items. One can convert between them freely using \fI\%the conversion functions\fP\&.
.sp
Actual Type of the integer can be checked using \fI\%item types API\fP\&.
.sp
An integer item is created with one of the four widths. Because integers\(aq \fI\%storage is bundled together with the handle\fP, the width cannot be changed over its lifetime.

Due to the fact that CBOR negative integers represent integers in the range [\-1, \-2^N], \fBcbor_set_uint\fP API is somewhat counter\-intuitive as the resulting logical value is 1 less. This behavior is necessary in order to permit uniform manipulation with the full range of permitted values. For example, the following snippet
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
cbor_item_t * item = cbor_new_int8();
cbor_mark_negint(item);
cbor_set_uint8(0);
.ft P

.SS Type 2 – Byte strings
.sp
CBOR byte strings are just (ordered) series of bytes without further interpretation (unless there is a \fI\%tag\fP). Byte string\(aqs length may or may not be known during encoding. These two kinds of byte strings can be distinguished using \fBcbor_bytestring_is_definite()\fP and \fBcbor_bytestring_is_indefinite()\fP respectively.
.sp
In case a byte string is indefinite, it is encoded as a series of definite byte strings. These are called \(dqchunks\(dq. For example, the encoded item

CBOR arrays, just like \fI\%byte strings\fP and \fI\%strings\fP, can be encoded either as definite, or as indefinite.
Definite arrays have a fixed size which is stored in the header, whereas indefinite arrays do not and are terminated by a special \(dqbreak\(dq byte instead.

CBOR maps are the plain old associative maps similar JSON objects or Python dictionaries.

Definite maps have a fixed size which is stored in the header, whereas indefinite maps do not and are terminated by a special \(dqbreak\(dq byte instead.

Every release is tested for memory correctness. You can run these tests by passing the \fB\-T memcheck\fP flag to \fBctest\fP\&. [1]

.SS Fuzz testing
.sp
Every release is tested using a fuzz test. In this test, a huge buffer filled with random data is passed to the decoder. We require that it either succeeds or fail with a sensible error, without leaking any memory. This is intended to simulate real\-world situations where data received from the network are CBOR\-decoded before any further processing.
.SS RFC conformance
.sp
\fIlibcbor\fP is, generally speaking, very faithful implementation of \fI\%RFC 7049\fP\&. There are, however, some limitations imposed by technical constraints.
.SS Bytestring length
.sp
There is no explicit limitation of indefinite length byte strings. [1] \fIlibcbor\fP will not handle byte strings with more chunks than the maximum value of \fBsize_t\fP\&. On any sane platform, such string would not fit in the memory anyway. It is, however, possible to process arbitrarily long strings and byte strings using the streaming decoder.
.IP [1] 5
\fI\%https://tools.ietf.org/html/rfc7049#section\-2.2.2\fP
.SS \(dqHalf\-precision\(dq IEEE 754 floats
.sp
As of C99 and even C11, there is no standard implementation for 2 bytes floats. \fIlibcbor\fP packs them as a \fIfloat <https://en.cppreference.com/w/c/language/type>\fP\&. When encoding, \fIlibcbor\fP selects the appropriate wire representation based on metadata and the actual value. This applies both to canonical and normal mode.

.SS Vision and principles
.sp
Consistency and coherence are one of the key characteristics of good software.
While the reality is never black and white, it is important libcbor
contributors are working towards the same high\-level goal. This document
attempts to set out the basic principles of libcbor and the rationale behind
them. If you are contributing to libcbor or looking to evaluate whether libcbor
is the right choice for your project, it might be worthwhile to skim through the
section below.
.SS Mission statement
.sp
\fIlibcbor\fP is the compact, full\-featured, and safe CBOR library that works
everywhere.
.SS Goals
.SS RFC\-conformance and full feature support
.sp
Anything the standard allows, libcbor can do.
.sp
\fBWhy?\fP Because conformance and interoperability is the point of defining
standards. Clients expect the support to be feature\-complete and
there is no significant complexity reduction that can be achieved by slightly
cutting corners, which means that the incremental cost of full RFC support is
comparatively small over \(dqalmost\-conformance\(dq seen in many alternatives.
.SS Safety
.sp
Untrusted bytes from the network are the typical input.
.sp
\fBWhy?\fP Because it is the client expectation. Vast majority of security
vulnerabilities are violations of contracts \-\- in other words, bugs \-\- anyway.
.SS Self\-containment
.sp
libcbor has no runtime dependencies.
.sp
\fBWhy?\fP Because any constraint imposed on libcbor has to be enforced
transitively, which is difficult and leads to incompatibilities and
distribution issues, especially in IoT applications.
.SS Portability
.sp
If you can compile C for it, libcbor will work there.
.sp
\fBWhy?\fP Lowest\-common\-denominator solution for system\-level and IoT software
was the original niche of libcbor. Users who rely on libcbor expect future
updates to work on their target platform.
.SS Stable and predictable API
.sp
libcbor will not break without a warning.
.sp
\fBWhy?\fP \fI\%Industry\-standard\fP versioning is a basic
requirement for production\-quality software. This is especially relevant in IoT
environments where updates may be costly.
.SS Performance
.sp
libcbor is fast and resource\-efficient by design
.sp
\fBWhy?\fP Because the main maintainer is an avid hater of slow bloated software.
Who wouldn\(aqt want more bang per their electricity buck?
