17 The waffle_dl functions provide a platform-independent interface for
18 dynamic OpenGL libraries. For each function, the parameter dl must be
19 one of:
20 WAFFLE_DL_OPENGL
21 WAFFLE_DL_OPENGL_ES1
22 WAFFLE_DL_OPENGL_ES2
23 WAFFLE_DL_OPENGL_ES3
24
25 For example, on Linux, the WAFFLE_DL_* enums map to libGL.so.1,
26 libGLESv1_CM.so.1, libGLESv2.so.2, and libGLESv2.so.2, respectively.
27
28 waffle_dl_can_open()
29 Test if a dynamic library can be opened.
30
31 waffle_dl_sym()
32 Get a symbol from a dynamic library.
33
35 Functions whose return type is bool return true on success and false on
36 failure. Functions whose return type is a pointer return NULL on
37 failure. Use waffle_error_get_info(3) to get information about any
38 errors.
39
41 If waffle fails to find the requested library on the system, then
42 WAFFLE_ERROR_UNSUPPORTED_ON_PLATFORM is emitted.
43
44 See waffle_error(3) for the complete list of waffle's error codes.
