Produce a string description of an error number. $child_error defaults
to $? if not specified. $os_error defaults to $! if not specified.
The algorithm is taken from perldoc -f system. Some sample output:
failed to execute: No such file or directory (-1)
died with signal 15, with coredump
exited with value 3
An options hashref can be specified as the first argument to add
information. Currently known keys:
* prog => str
Program name/path, to include in error messages:
/usr/bin/foo failed to execute: Permission denied (-1)
foo died with signal 15, with coredump
/usr/bin/foo exited with value 3
SEE ALSO
Process::Status provides a lightweight OO interface for $?. I recommend
this module now over Proc::ChildError.
IPC::System::Simple provides a replacement for Perl's system(), with
the difference that it will print a diagnostic error message similar to
what Proc::ChildError provides. You only need to do use
IPC::System::Simple qw(system) and use system() as usual. Recommended.
