|
||
|
|
* 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

*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
|
||
|
|
* _TSCHAR *pathname - name of file to spawn
|
||
|
|
* _TSCHAR **argv - vector of arguments
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* returns exit code of child process
|
||
|
|
* returns -1 if fails
