/* Execute a command, optionally redirecting any of the three standard file
|
|
descriptors to /dev/null. Return its exit code.
|
|
If it didn't terminate correctly, exit if exit_on_error is true, otherwise
|
|
return 127.
|
|
progname is the name of the program to be executed by the subprocess, used
|
|
for error messages.
|
|
prog_path is the file name of the program to be executed by the subprocess.
|
|
If it contains no slashes, a search is conducted in $PATH. An operating
|
|
system dependent suffix is added, if necessary.
|
|
prog_argv is the array of strings that the subprocess shall receive in
|
|
argv[]. It is a NULL-terminated array. prog_argv[0] should normally be
|
|
identical to prog_path.
|
|
If directory is not NULL, the command is executed in that directory. If
|
|
prog_path is a relative file name, it resolved before changing to that
|
|
directory. The current directory of the current process remains unchanged.
|
|
If ignore_sigpipe is true, consider a subprocess termination due to SIGPIPE
|
|
as equivalent to a success. This is suitable for processes whose only
|
|
purpose is to write to standard output.
|
|
If slave_process is true, the child process will be terminated when its
|
|
creator receives a catchable fatal signal.
|
|
If termsigp is not NULL, *termsig will be set to the signal that terminated
|
|
the subprocess (if supported by the platform: not on native Windows
|
|
platforms), otherwise 0.
|
|
It is recommended that no signal is blocked or ignored while execute()
|
|
is called. See spawn-pipe.h for the reason. */
