NAME

POSIX::RT::Spawn - interface to the posix_spawn function

SYNOPSIS

  use POSIX::RT::Spawn;

  my $pid = spawn 'command', 'arg1', 'arg2'
      or die "failed to spawn: $!";
  waitpid $pid, 0;
  die "command failed with status: ", $?>>8 if $?;

DESCRIPTION

The POSIX::RT::Spawn module provides an interface to the posix_spawn(2) function for creating new processes.

FUNCTIONS

spawn

  $pid = spawn 'echo', 'hello world'

Does exactly the same thing as system LIST, except the parent process does not wait for the child process to exit. Also, the return value is the child pid on success, or false on failure.

See "system" in perlfunc for more details.

TODO

• Allow the user to alter posix_spawn settings using package variables, e.g. $POSIX::RT::Spawn::Flags{RESETIDS} = 1 or $POSIX::RT::Spawn::Flags |= &POSIX_SPAWN_RESETIDS

• Allow the user to lexically replace the ops that use fork/exec (e.g. backticks, open, system) with versions that use posix_spawn.
