* Copyright (c) 1985-1991, Microsoft Corporation. All rights reserved.
*
*Purpose:
* defines _spawnvp() - spawn a child process; search along PATH
*
*Revision History:
* 04-15-84 DFW written
* 10-29-85 TC added spawnvpe capability
* 12-11-87 JCR Added "_LOAD_DS" to declaration
* 11-20-89 GJF Fixed copyright, alignment. Added const to arg types
* for filename and argv.
* 03-08-90 GJF Replaced _LOAD_DS with _CALLTYPE1, added #include
* <cruntime.h> and removed #include <register.h>
* 05-21-90 GJF Fixed stack checking pragma syntax.
* 08-24-90 SBM Removed check_stack pragma since workhorse _spawnve
* does stack checks
* 09-27-90 GJF New-style function declarator.
* 01-17-91 GJF ANSI naming.
* 02-14-90 SRW Use NULL instead of _environ to get default.

*int _spawnvp(modeflag, filename, argv) - spawn a child process (search PATH)
*
*Purpose:
* Spawns a child process, with search along PATH variable.
* formats the parameters and calls _spawnve to do the actual work. The
* NULL environment pointer indicates the new process will inherit the
* parents process's environment. NOTE - at least one argument must be
* present. This argument is always, by convention, the name of the file
* being spawned.
*
*Entry:
* int modeflag - mode to spawn (WAIT, NOWAIT, or OVERLAY)
* only WAIT and OVERLAY currently supported
* char *pathname - name of file to spawn
* char **argv - vector of arguments
*
*Exit:
* returns exit code of child process
* returns -1 if fails
*
*Exceptions:
*
