void ginq_char_up_vec(Gint *err_ind, Gvec *char_up_vec);
- (Integer, Output) - If the inquired values cannot be returned correctly, a non-zero error indicator is returned in ERRIND, otherwise a zero is returned. Consult "User's Guide for NCAR GKS-0A Graphics" for a description of the meaning of the error indicators.
