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(GLCDATAPOINTER) to obtain access to these
data in a thread-safe manner.
ERRORS
GLCSTATEERROR is generated if the issuing thread has no current GLC
context.
