ffffgggglllluuuuEEEErrrrrrrroooorrrrSSSSttttrrrriiiinnnngggg produces an error string from a GL or GLU error code. The
string is in ISO Latin 1 format. For example,
ffffgggglllluuuuEEEErrrrrrrroooorrrrSSSSttttrrrriiiinnnngggg(GGGGLLLL____OOOOUUUUTTTT____OOOOFFFF____MMMMEEEEMMMMOOOORRRRYYYY) returns the string _o_u_t _o_f _m_e_m_o_r_y.
The standard GLU error codes are GGGGLLLLUUUU____IIIINNNNVVVVAAAALLLLIIIIDDDD____EEEENNNNUUUUMMMM, GGGGLLLLUUUU____IIIINNNNVVVVAAAALLLLIIIIDDDD____VVVVAAAALLLLUUUUEEEE, and
GGGGLLLLUUUU____OOOOUUUUTTTT____OOOOFFFF____MMMMEEEEMMMMOOOORRRRYYYY. Certain other GLU functions can return specialized
error codes through callbacks. See the ggggllllGGGGeeeettttEEEErrrrrrrroooorrrr reference page for the
list of GL error codes.
EEEERRRRRRRROOOORRRRSSSS
NNNNUUUULLLLLLLL is returned if _e_r_r_o_r is not a valid GL or GLU error code.
