Detailed Description

APR-util Versioning Interface.

APR-util's Version

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 APU by use of the compile-time constants and the use of the run-time query function.

APU version numbering follows the guidelines specified in:

Define Documentation

#define APU_IS_DEV_STRING   "-dev"

The symbol APU_IS_DEV_VERSION is only defined for internal, "development" copies of APU. It is undefined for released versions of APU. Internal: string form of the "is dev" flag


major version Major API changes that could cause compatibility problems for older programs such as structure size changes. No binary compatibility is possible across a change in the major version.


minor version Minor API changes that do not cause binary compatibility problems. Reset to 0 when upgrading APU_MAJOR_VERSION


patch level The Patch Level never includes API changes, simply bug fixes. Reset to 0 when upgrading APR_MINOR_VERSION


Properly quote a value as a string in the C preprocessor

#define APU_STRINGIFY_HELPER (  )     #n

Helper macro for APU_STRINGIFY

An alternative formatted string of APR's version
