NAME

sys.ops - System Interaction Opcodes

DESCRIPTION

Operations that allow the user to interact with the system.

When making changes to any ops file, run make bootstrap-ops to regenerate all generated ops files.

spawnw(out INT, in STR)
Spawn a subprocess whose program name and arguments are contained in the string $2 and wait for it to finish. The return status, which is very system-dependent, goes in $1.
spawnw(out INT, invar PMC)
Spawn a subprocess whose program name and arguments are contained in the array $2 and wait for it to finish. The return status, which is very system-dependent, goes in $1.GH #362: spawnw() should itself handle splitting up command-line arguments, rather than depending on the shell to do so in potentially unsafe manner. See https://github.com/parrot/parrot/issues/362 (formerly https://trac.parrot.org/parrot/ticket/847).GH #369: spawnw() should return something less system-dependent, and more object-like. See https://github.com/parrot/parrot/issues/369.
err(out INT)
Store the system error code in $1.
err(out STR)
Store the system error message in $1.
err(out STR, in INT)
Get the system error message for the system error code $2 and store it in $1.
time(out INT)
Puts the current system time (represented as a whole number of seconds) in $1.
time(out NUM)
Puts the current system time (represented as a number of seconds, with microseconds) in $1.
sleep(in INT)
sleep(in NUM)
Sleep for $1 seconds.
