-
-Number
-
-    EGL Extension #131
-
-Dependencies
-
-    EGL 1.4 is required.
-
-Overview
-
-    When an application has to query the name of a DRI driver and for
-    obtaining driver's option list (UTF-8 encoded XML) of a DRI
-    driver the below functions are useful.
-
-New Procedures and Functions
-
-    const char* eglGetDisplayDriverConfig(EGLDisplay disp, const char *driverName);
-    const char* eglGetDisplayDriverName(EGLDisplay disp);
-
-Description
-
-    First, create an EGLDisplay, EGLContext, EGLSurface then `eglMakeCurrent()` and
-    pass this EGLDisplay as parameter to `eglGetDisplayDriverName`
-
-    After we get the driverName to obtain configs pass it to `eglGetDisplayDriverConfig`
-
-    If the EGLDisplay is not queryable like on haiku systems these new functions will
-    return NULL
-
-New Tokens
-
-    No new tokens
