PEXPCAttributes5_2 *PEXGetPipelineContext5_2( Display *display, PEXPipelineContext context, unsigned long *value_mask )
PEXPCAttributes *PEXGetPipelineContext( Display *display, PEXPipelineContext context, unsigned long *value_mask )
A pointer to pipeline context values; a null pointer if unsuccessful.
Invoke PEXGetPipelineContext5_2 to obtain the requested attribute values of the pipeline context. You must use the 5.2 form of the function unless all aspects of the components you wish to get were defined in PEX 5.0 or 5.1. Note that each of the two forms uses a different structure for the returned parameter.
Use the value_mask to indicate which attribute values you are requesting. Invoke the PEXSetPCAttributeMask and PEXSetPCAttributeMaskAll functions to set up the value_mask.
PEXlib allocates the memory for the return value. Invoke the PEXFreePCAttributes5_2 (or PEXFreePCAttributes as appropriate) function to deallocate the memory.
