Detailed Description

Versioning API for libapreq.

There are several different mechanisms for accessing the version. There is a string form, and a set of numbers; in addition, there are constants which can be compiled into your application, and you can query the library being used for its actual version.

Note that it is possible for an application to detect that it has been compiled against a different version of libapreq by use of the compile-time constants and the use of the run-time query function.

libapreq version numbering follows the guidelines specified in:
