+
+ This extensions provides a way to convert pointers in an AGP memory

+Additions to Chapter 3 the GLX 1.4 Specification (Functions and Errors)
+
+ Add a new section, 3.6 as follows:
+
+ 3.6 AGP Memory Access
+
+ On "PC" computers, AGP memory can be allocated with glXAllocateMemoryNV
+ and freed with glXFreeMemoryNV. Sometimes it's useful to know where a
+ block of AGP memory is located with respect to the start of the AGP
+ aperture. 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
