DESCRIPTION
gglluuQQuuaaddrriiccCCaallllbbaacckk is used to define a new callback to be used by a quadrics object.
If the specified callback is already defined, then it is replaced. If
_C_a_l_l_B_a_c_k_F_u_n_c is NULL, then any existing callback is erased.
The one legal callback is GGLLUU__EERRRROORR:
-
GGLLUU__EERRRROORR
-
The function is called when an error is encountered. Its single argument
is of type GLenum, and it indicates the specific error that occurred.
Character strings describing these errors can be retrieved with the
gglluuEErrrroorrSSttrriinngg call.
