fork_no_output
|
|
|
|
Forks a process for the given command array and returns the process
|
|
ID for the forked process. Since no I/O is needed for the pipes, no
|
|
STDOUT/STDERR pipes are returned to the caller.
|
|
|
|
Arguments:
|
|
$fork_id - unique identifer to use for tracking the forked process
|
|
@command - command and parameter array to execute in the forkec process
|
|
|
|
Returns:
|
|
$pid - process identifer for the forked process
|
|
|
|
Globals:
|
|
None
|
|
|
|
Error:
|

None
|

Example:
|

$pid = xCAT::DSHCore->fork_no_output('hostname1PID', @command_array);

Forks a process for the given command array and returns the process
