22 * @brief APR-util Versioning Interface
26 * There are several different mechanisms for accessing the version. There
27 * is a string form, and a set of numbers; in addition, there are constants
28 * which can be compiled into your application, and you can query the library
29 * being used for its actual version.
31 * Note that it is possible for an application to detect that it has been
32 * compiled against a different version of APU by use of the compile-time
33 * constants and the use of the run-time query function.
35 * APU version numbering follows the guidelines specified in:
37 * http://apr.apache.org/versioning.html

42 "Foundation or its licensors, as applicable."
44 /* The numeric compile-time version constants. These constants are the
45 * authoritative version numbers for APU.
49 * Major API changes that could cause compatibility problems for older
50 * programs such as structure size changes. No binary compatibility is
51 * possible across a change in the major version.
53 #define APU_MAJOR_VERSION 1
56 * Minor API changes that do not cause binary compatibility problems.
57 * Reset to 0 when upgrading APU_MAJOR_VERSION
59 #define APU_MINOR_VERSION 5
62 * The Patch Level never includes API changes, simply bug fixes.
63 * Reset to 0 when upgrading APR_MINOR_VERSION
65 #define APU_PATCH_VERSION 3
68 * The symbol APU_IS_DEV_VERSION is only defined for internal,
69 * "development" copies of APU. It is undefined for released versions
