FreeBSD erroneously returns EINVAL in that case. As EINVAL is Just what is eye-catching: +- can't be compared to whitespace at all. Whitespace is not subject sequence (2) but initial sequence (1) according to POSIX. Moreover, POSIX clearly allows EINVAL for strtol(): "If no conversion could be performed, 0 shall be returned and errno may be set to [EINVAL]" Reading POSIX will really help you with this issue. -- http://ache.pp.ru/Received on Thu Jan 20 2005 - 19:55:04 UTC
