NAME

Error::Wait - User-friendly version of $?

SYNOPSIS

use Error::Wait;
system('/no/such/file') == 0 or die $?;   # "No such file or directory"
system('/bin/false')    == 0 or die $?;   # "Exited: 1"
system('kill -HUP $$')  == 0 or die $?;   # "Killed: HUP"

DESCRIPTION

Error::Wait overloads the stringification of $? to provide sensible error messages. Numeric and boolean operations continue to work as usual, so code using $? >> 8 won't break.

SEE ALSO

"$?" in perlvar, "system" in perlfunc, "WAIT" in POSIX

KNOWN ISSUES

$? and the wait.h macros aren't really portable.
