SYNOPSIS    [Toc]    [Back]

     #include <dmedia/fx_buffer.h>

     DMboolean dmFXIsGLExtensionSupported    [Toc]    [Back]
	   ( PRX_ScanlineBuffer	buffer,
	     const char	*extension )

PARAMETERS    [Toc]    [Back]

     buffer	 The destination scanline buffer to query.

     extension	 The GL	extension to look for.

DESCRIPTION    [Toc]    [Back]

     dmFXIsGLExtensionSupported	checks to see if the given extension is
     supported by the underlying GL context of the given scanline buffer.

     It	is legal to call dmFXIsGLExtensionSupported with a scanline buffer
     which does	not have a GL rendering	context.  In this case
     dmFXIsGLExtensionSupported	will return DM_FALSE.

RETURN VALUES    [Toc]    [Back]

     DM_FALSE is returned if the given GL extension is not
	  supported by the given scanline buffer, or if	the scanline buffer
	  does not have	a GL rendering context.

     DM_TRUE is	returned if the	given extension	is supported
	  by the scanline buffer.
