|
|
* 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:
