waffle_dl, waffle_dl_can_open, waffle_dl_sym − platform−independent interface to dynamic libraries
#include <waffle.h>
bool waffle_dl_can_open(int32_t dl); |
||
void* waffle_dl_sym(int32_t dl, const char* symbol); |
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.
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.
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.
Please report bugs or and feature requests to https://gitlab.freedesktop.org/mesa/waffle/issues.
