Function Documentation

int snd_dlclose (  void *    handle )

Closes a dynamic library - ALSA wrapper for dlclose. Parameters: handle  Library handle, similar to dlclose. Returns: Zero if successful, otherwise an error code. This function can emulate dynamic linking for the static build of the alsa-lib library.

void* snd_dlopen (  const char *    name, int    mode )

Opens a dynamic library - ALSA wrapper for dlopen. Parameters: name  name of the library, similar to dlopen. mode  mode flags, similar to dlopen. Returns: Library handle if successful, otherwise NULL. This function can emulate dynamic linking for the static build of the alsa-lib library. In that case, name is set to NULL.

void* snd_dlsym (  void *    handle, const char *    name, const char *    version )

Resolves a symbol from a dynamic library - ALSA wrapper for dlsym. Parameters: handle  Library handle, similar to dlsym. name  Symbol name. version  Version of the symbol. This function can emulate dynamic linking for the static build of the alsa-lib library. This special version of the dlsym function checks also the version of the symbol. A versioned symbol should be defined using the SND_DLSYM_BUILD_VERSION macro.
