Is process.h part of Standard C++?

As above.

I cannot find it in the library list of 'Practical C++' book or under MSDN C++ reference section.

Thanx in advance.

process.h covers stuff like execl(), spawn() and sometimes
system()

There is no process.h in ansi C.

And even though system() is standard, system() is traditionally defined in stdlib.h

Borland compilers all implement process.h to my knowledge.
