API documentation for libmpg123, libout123, and libsyn123
Note:
This API doc is automatically generated from the current development version that you can get via Subversion or as a daily snapshot from http://mpg123.org/snapshot.
There may be differences (additions) compared to the latest stable release. See
NEWS.libmpg123,
NEWS.libout123,
NEWS.libsyn123,
and the overall NEWS file on libmpg123 versions and important changes between them.
Let me emphasize that the policy for the lib*123 family is to always stay backwards compatible -- only additions are planned (and it's not yet planned to change the plans;-).

◆ MPG123_EXPORT

Defines needed for MS Visual Studio(tm) DLL builds. Every public function must be prefixed with MPG123_EXPORT. When building the DLL ensure to define BUILD_MPG123_DLL. This makes the function accessible for clients and includes it in the import library which is created together with the DLL. When consuming the DLL ensure to define LINK_MPG123_DLL which imports the functions from the DLL.
