spawnlp()                Execute Program Using Argument List and PATH

 #include <process.h>
 #include <stdio.h>

 int        spawnlp(modeflag,pathname,arg0,arg1...,argn,NULL)
 int        modeflag;                    Execution mode for parent process
 char       *pathname;                   Path name of file to be executed
 char       *arg0,*arg1,...,*argn;       List of pointers to argument

    spawnlp() operates identically to spawnl(), with one exception:  If
    'pathname' is not found as described in spawnl(), then spawnlp() will
    use the DOS PATH to continue the search for pathname.  With that
    single exception, the two functions are identical; see spawnl() for a
    complete description.

  -------------------------------- Example ---------------------------------

    The following statements transfer execution to the child process
    "child.exe" and pass it the three arguments "child", "arg1", and
    "arg2".  "child.exe" will be found in the current directory or any
    PATH directory.  The exit status of the child is printed upon return.

    #include <process.h>    /* for 'spawnlp' and 'P_WAIT' */
    #include <stdio.h>      /* for 'printf' and 'NULL' */
    #include <stdlib.h>     /* for 'errno' */
    #include <errno.h>      /* for 'ENOENT' and 'ENOMEM' */

    main()
    {
        int result;

        result = spawnlp(P_WAIT,"child.exe","child","arg1","arg2",NULL);
       if (result != -1)
           printf("exit status of child.exe = %d\n", result);
       else {
           if (errno == ENOENT) {
               printf("child.exe not found in current directory,\n");
               printf("  or in any PATH directory.\n");
           } else if (errno == ENOMEM)
               printf("not enough memory to execute child.exe\n");
           else
               printf("error #%d trying to spawn child.exe\n", errno);
        }
    }
