/* 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.

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 pipe.h for the reason. */
