Error -151 and NewGWorld

Q: I received an error code of -151 from NewGWorld when creating a very large off-screen bitmap. Does this mean not enough memory? If so, can I count on it not to change in future versions of the system? It's not listed as one of the possible errors in Inside Macintosh Volume VI.

A: The error -151 is cTempMemErr, "failed to allocate memory for temporary structures," or in other words, there wasn't enough temporary memory available for NewGWorld. NewGWorld returns this error after it receives a memFullErr from TempNewHandle. This was inadvertently left out of Inside Macintosh Volume VI but does appear in the MPW interface files. You can count on this error code in future versions of system software.

See Inside Macintosh: Memory or the Memory Management chapter of Inside Macintosh Volume VI for more information about temporary memory.
