       int spawnl( int mode, char *path, char *arg0,
                       char *arg1, ..., NULL )
       int spawnle( int mode, char *path, char *arg0,
                       char *arg1, ..., NULL, char *envp[] )
       int spawnlp( int mode, char *path, char *arg0,
                       char *arg1, ..., NULL )
       int spawnlpe( int mode, char *path, char *arg0,
                       char *arg1, ..., NULL, char *envp[] )
       int spawnv( int mode, char *path, char *argv )
       int spawnve( int mode, char *path, char *argv, char *envp[] )

       int spawnvpe( int mode, char *path, char *argv, char *envp[] )

       - prototype in process.h

       - creates & runs child processes
       - mode is P_WAIT which puts parent process "on hold" until child
         completes execution; P_NOWAIT which continues to run parent
         while child runs (not supported yet); or P_OVERLAY which overlays
         child in memory location formerly occupied by parent (same as
         exec... call)
       - use P_WAIT to perform a DOS shell
       - returns 0 for SUCCESS and non-zero for failure based on the
         errorlevel set by the application

       - see   exec...
