Sometimes it's useful to know where a - block of AGP memory is located with respect to the start of the AGP - aperature. The function - - GLuint glXGetAGPOffsetMESA( const GLvoid *pointer ) - - Returns the offset of the given memory block from the start of AGP - memory in basic machine units (i.e. bytes). If pointer is invalid - the value ~0 will be returned. - -GLX Protocol - - None. This is a client side-only extension. - -Errors - - glXGetAGPOffsetMESA will return ~0 if the pointer does not point to - an AGP memory region. - -New State - - None - -Revision History - - 20 September 2002 - Initial draft - 2 October 2002 - finished GLX chapter 3 additions - 27 July 2004 - use unsigned int instead of GLuint, void instead of GLvoid |
