I think that pragma works like most others in CW, which is covered under
"Pragma Scope" in the IDE online help. It actually says they >don't<
work from inside a precompiled header, though they might work in a
regular (non precompiled) header. This online help talks about the
pragma scope ending at the end of the file, though I think they really
mean "translation unit", which is the source file with all the non
precompiled includes expanded by the preprocessor.
You almost certainly >don't< want this stack cleanup globally. That
would greatly inflate and slow your code where not needed.
So you should be able to use "#pragma stack_cleanup on" above the
specific function(s) you want, followed by "#pragma stack_cleanup reset"
after the function(s).
But if you have any doubt about what it's really doing, use the IDE
"Disassemble" command and verify it does the cleanup you want.
