Error::Wait - User-friendly version of C<$?>

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 the perlvar manpage, system in the perlfunc manpage, system in the perlport manpage

KNOWN ISSUES

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