NAME¶

waffle_dl, waffle_dl_can_open, waffle_dl_sym - platform-independent interface to dynamic libraries

SYNOPSIS¶

#include <waffle.h>

bool waffle_dl_can_open(int32_t dl);

void* waffle_dl_sym(int32_t dl, const char* symbol);

DESCRIPTION¶

The waffle_dl functions provide a platform-independent interface for dynamic OpenGL libraries. For each function, the parameter dl must be one of:

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()

waffle_dl_sym()

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.
