DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

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

ASSOCIATED GETS    [Toc]    [Back]

     glcGetPointer with	argument GLC_DATA_POINTER
