waffle_dl3
Platform-independent interface to dynamic libraries
Usage
#include <waffle.h>
bool waffle_dl_can_open(int32_t dl);
void* waffle_dl_sym(int32_t dl, const char* symbol);
Overview
The waffle_dl functions provide a platform-independent interface for dynamic OpenGL libraries. For each function, the parameter dl must be one of:
WAFFLE_DL_OPENGL
WAFFLE_DL_OPENGL_ES1
WAFFLE_DL_OPENGL_ES2
WAFFLE_DL_OPENGL_ES3
For example, on Linux, the WAFFLE_DL_* enums map to libGL.so.1, libGLESv1_CM.so.1, libGLESv2.so.2, and libGLESv2.so.2, respectively.
waffle_dl_can_open()
Test if a dynamic library can be opened.
waffle_dl_sym()
Get a symbol from a dynamic library.
Return value
Functions whose return type is bool return true on success and false on failure. Functions whose return type is a pointer return NULL on failure. Use waffle_error_get_info(3) to get information about any errors.
Errors
If waffle fails to find the requested library on the system, then WAFFLE_ERROR_UNSUPPORTED_ON_PLATFORM is emitted.
See waffle_error(3) for the complete list of waffle's error codes.
