You can set $! to any integer, and its return value is mapped to the
corresponding system error. For example, under Mac OS X:
[EMAIL PROTECTED] pudge]$ perl -le 'for (0..20) { $! = $_; print $! }'
Operation not permitted
No such file or directory
No such process
Interrupted system call
Input/output error
Device not configured
Argument list too long
Exec format error
Bad file descriptor
No child processes
Resource deadlock avoided
Cannot allocate memory
Permission denied
Bad address
Block device required
Device busy
File exists
Cross-device link
Operation not supported by device
Not a directory
$^E works similarly.
A better option might b e $@, which can be set to arbitrary error values.
