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. */
