Runner - Run an external program through fork, with timeout and other signal management
This package is NOT an object oriented package
my ($status, $killed) = RunExt(-cmd $cmd, -stdin $stdin, -stdout $stdout, -stderr $sterr, -timeout $timeout);
PARAMETERS:
-cmd = The external command whith its parameters. -stdin = The standard input, if redirected (a file name, or anything you can pass to open) -stdout = The standard output, if redirected (a file name, or anything you can pass to open) -stderr = The standard error, if redirected (a file name, or anything you can pass to open) -timeout = The timeout in seconds. No timeout if -1
RETURNED VALUES: $status ==> the return value of the child $timeout ==> 0 if OK -1 if the child was killed by timeout -2 if the child was killed by TERM (ctrl-C, qdel, ...)
The cmd is executed, it may be killed if a TERM signal or an ALMR is received. The child is then killed with a TERM, followed by a KILL signal: it should return in any circumstance
my $pid = RunExtNoWait(-cmd $cmd, -stdin $stdin, -stdout $stdout, -stderr $sterr, -timeout $timeout);
PARAMETERS:
-cmd = The external command whith its parameters. -stdin = The standard input, if redirected (a file name, or anything you can pass to open) -stdout = The standard output, if redirected (a file name, or anything you can pass to open) -stderr = The standard error, if redirected (a file name, or anything you can pass to open)
RETURNED VALUE: $pid ==> the process Id of the child
The cmd is executed, but the sub returns without waiting for the child's death. The children started may be killed if a TERM signal or an ALARM signal are received. The child is then killed with a TERM signal. NO KILL signal is sent to the child, terminating the child in a graceful way. If I don't have to wait, I am less violent...
