Detailed Description

APR-iconv Versioning Interface.

APR-iconv'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 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 Documentation

#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.


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 API_MAJOR_VERSION


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

#define API_STRINGIFY_HELPER (  )     #n

Helper macro for API_STRINGIFY



The formatted string of API's version



                             ##API_MINOR_VERSION ##, \
An alternative formatted string of APR's version
