glcDataPointer(3G)

NAME
     glcDataPointer - assign a value to GLC_DATA_POINTER


C SPECIFICATION
     void glcDataPointer( GLvoid *inPointer )


PARAMETERS
     inPointer  Specifies the value to assign to GLC_DATA_POINTER.


DESCRIPTION
     glcDataPointer assigns the value inPointer to the variable
     GLC_DATA_POINTER. It is used for access to client data from a callback
     function.

     glcDataPointer provides a way to store in a GLC context a pointer to
     arbitrary application data.  A GLC callback function can subsequently use
     the command glcGetPointer(GLC_DATA_POINTER) to obtain access to these
     data in a thread-safe manner.

ERRORS
     GLC_STATE_ERROR is generated if the issuing thread has no current GLC
     context.

ASSOCIATED GETS
     glcGetPointer with argument GLC_DATA_POINTER
