WAFFLE_DL(3) Waffle Manual WAFFLE_DL(3) NAME waffle_dl, waffle_dl_can_open, waffle_dl_sym - platform-independent inter- face 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 dy- namic 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, lib- GLESv1_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 WAF- FLE_ERROR_UNSUPPORTED_ON_PLATFORM is emitted. See waffle_error(3) for the complete list of waffle's error codes. ISSUES Please report bugs or and feature requests to https://gitlab.freedesktop.org/mesa/waffle/issues.
