◆ R_CheckExtension()

bool R_CheckExtension ( const char * extension )

inlinestatic

Checks for an OpenGL extension that was announced via the OpenGL ext string. If the given extension string includes a placeholder (###), several types are checked. Those from the ARB, those that official extensions (EXT), and those from OpenGL ES (OES).

Parameters

extension The extension string to check. Might also contain placeholders. E.g. "GL_###_framebuffer_object", GL_ARB_framebuffer_object

Returns: true if the extension was announced by the OpenGL driver, false otherwise.
