Process and Environment Control in Visual C++

[u***@sta.samsung.com]

I have some questions pertaining to Process and Environment Control in
Visual C++ (http://msdn2.microsoft.com/en-us/library/d6dtz42k(Vs.
80).aspx).

1). Between spawn and exec, which function call is preferable to use,
or are they equivalent?

2). Does Windows Mobile support these calls?

Thanks,

1). Between spawn and exec, which function call is preferable to use,
or are they equivalent?

As mentioned there, Calling _exec(...) is equivalent to calling _spawn(_P_OVERLAY, ...).
So, _spawn() is more functional than _exec() at least.

2). Does Windows Mobile support these calls?

As far as I'd read the CRT source code (dospawn.c), both _exec()
and _spawn() just call CreateProcess() finally.
If the API function has restriction on the mobile versions of Windows,
both _exec() and _spawn() also.

Sorry, I don't know more.
