- * posix_spawnp
- *
- * Description:	Create a new process from the process image corresponding to
- *		the supplied 'file' argument and the parent processes path
- *		environment.
- *
- * Parameters:	pid				Pointer to pid_t to receive the
- *						PID of the spawned process, if
- *						successful and 'pid' != NULL
- *		file				Name of image file to spawn
- *		file_actions			spawn file actions object which
- *						describes file actions to be
- *						performed during the spawn
- *		attrp				spawn attributes object which
- *						describes attributes to be
- *						applied during the spawn
- *		argv				argument vector array; NULL
- *						terminated
- *		envp				environment vector array; NULL
- *						terminated
- *
- * Returns:	0				Success
- *		!0				An errno value indicating the
- *						cause of the failure to spawn
- *
- * Notes:	Much of this function is derived from code from execvP() from
- *		exec.c in libc; this common code should be factored out at
- *		some point to prevent code duplication or desynchronization vs.
- *		bug fixes applied to one set of code but not the other.
