*int _spawnv(modeflag, pathname, argv) - spawn a child process
|
|
*
|
|
*Purpose:
|
|
* Spawns a child process.
|
|
* formats the parameters and calls _spawnve to do the actual work. The
|
|
* NULL environment pointer indicates that 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 implemented
|
|
* char *pathname - file to spawn
|
|
* char **argv - vector of arguments
|
|
*
|
|
*Exit:
|
|
* returns exit code of child process
|
|
* if fails, returns -1
|
|
*
|
|
*Exceptions:
|
|
*
