Thanks for the followup.

and there is no mention of errno in the man page.  Errno is generally
set by system calls (which malloc isn't).  The man pages will

you should check errno.

Maybe I missed part of the thread that states which man page the snipet comes from, but my man page does mention errno (Tiger 10.4.4/Xcode 2.2.1).

If successful, the malloc(), calloc(), and valloc() functions return a
pointer to allocated memory. If there is an error, they return a NULL
pointer and set errno to ENOMEM.

I haven't updated to 2.2.1 yet; my (2.2 install) man page does not say this.


(The man
page also warns against relying too heavily on this in case you use
custom malloc implementations which may not conform to this.)

This may be the best advice :-}

Regards,

Justin
