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   ""

The symbol APU_IS_DEV_VERSION is only defined for internal, "development" copies of APU. It is undefined for released versions of APU.

Definition at line 76 of file apu_version.h.

#define APU_MAJOR_VERSION   1

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.

Definition at line 50 of file apu_version.h.

#define APU_MINOR_VERSION   5

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

Definition at line 56 of file apu_version.h.

#define APU_PATCH_VERSION   2

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

Definition at line 62 of file apu_version.h.

#define APU_VERSION_STRING

Value:

APU_STRINGIFY(APU_MAJOR_VERSION) "." \
     APU_STRINGIFY(APU_MINOR_VERSION) "." \
     APU_STRINGIFY(APU_PATCH_VERSION) \
     APU_IS_DEV_STRING

The formatted string of APU's version

Definition at line 88 of file apu_version.h.

#define APU_VERSION_STRING_CSV

Value:

APU_MAJOR_VERSION ##, \
                             ##APU_MINOR_VERSION ##, \
                             ##APU_PATCH_VERSION

An alternative formatted string of APR's version
