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:
           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.
