+/* 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.
+
+   dll_dirs is, on Windows platforms, a NULL-terminated list of directories
+   that contain DLLs needed to execute the program, or NULL if none is needed.
+   On other platforms, always pass NULL.
+
+   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.  */
