 spawnvp()               Execute Program Using Arg Array, PATH

 #include   <process.h>

 int        spawnvp(modeflag,pathname,argv);
 int        modeflag;                    execution mode for parent process
 char       *pathname;                   path name of file to be executed
 char       *argv[];                     Array of pointers to arguments

    spawnvp() operates exactly like spawnv(), with one exception:  If
    'pathname' is not found as described in spawnv(), then spawnvp() uses
    the current directory, followed by the DOS PATH to continue the
    search for the path name.  Otherwise, the two functions are
    identical; see spawnv() for a complete description.

   Portability:     MS-DOS only.

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

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

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

           char *args[] = {"child", "arg1", "arg2", NULL};

           main()
           {
               int result;

               result = spawnvp(P_WAIT, "child.exe", args);
               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);
               }
