|const char *||api_version_string (void)|
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 API by use of the compile-time constants and the use of the run-time query function.
API version numbering follows the guidelines specified in:
|#define API_IS_DEV_STRING "-dev"|
Internal: string form of the "is dev" flag
The symbol API_IS_DEV_VERSION is only defined for internal, "development" copies of API. It is undefined for released versions of API.
|#define API_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.
|#define API_MINOR_VERSION 2|
minor version Minor API changes that do not cause binary compatibility problems. Reset to 0 when upgrading API_MAJOR_VERSION
|#define API_PATCH_VERSION 0|
patch level The Patch Level never includes API changes, simply bug fixes. Reset to 0 when upgrading API_MINOR_VERSION
Properly quote a value as a string in the C preprocessor
Helper macro for API_STRINGIFY
API_MAJOR_VERSION ##, \ ##API_MINOR_VERSION ##, \ ##API_PATCH_VERSION
|void api_version||(||apr_version_t *||pvsn||)|
Return APR-iconv's version information information in a numeric form.
|pvsn||Pointer to a version structure for returning the version information.|
|const char* api_version_string||(||void||)|
Return API's version information as a string.
