The offending command is ignored, and has no other side effect +than to set the error flag. +.P +When an error flag is set, +results of a GL operation are undefined only if _const(OUT_OF_MEMORY) +has occurred. +In all other cases, +the command generating the error is ignored and has no effect on the GL state +or frame buffer contents. +If the generating command returns a value, it returns 0. +If _cmnd itself generates an error, it returns 0. +.SH NOTES +_const(TABLE_TOO_LARGE) was introduced in GL version 1.2. +.SH ERRORS +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). +In this case _cmnd returns 0. -- cgit v1.2.3
