Process::Status - a handle on process termination, like $?
When you run a system command with
qx`` or a number of other mechanisms,
the process termination status gets put into
$? as an integer.
it's a value of type
and it stores a few pieces of data in different bits.
Process::Status just provides a few simple methods to make it easier to inspect.
Almost the sole reason it exists is for its
which can be passed to a pretty printer to dump
$? in a somewhat more human-readable format.
Methods called on
Process::Status without first calling a constructor will work on an implicitly-constructed object using the current value of
To get an object for a specific value,
you can call
new and pass an integer.
You can also call
new with no arguments to get an object for the current value of
if you want to keep that ugly variable out of your code.
my $ps = Process::Status->new( $pid_t ); my $ps = Process::Status->new; # acts as if you'd passed $?
This returns the value of the
pid_t integer, as you might have found in
This method returns true if the
pid_t is zero.
This method returns the exit status of the
This returns the signal caught by the process, or zero.
This method returns true if the process dumped core.
This method returns a hashref describing the status. Its exact contents may change over time; it is meant for human, not computer, consumption.
