check_stack

#pragma check_stack([ {on | off}] )
#pragma check_stack{+ | –}

Instructs the compiler to turn off stack probes if off (or ) is specified, or to turn on stack probes if on (or +) is specified. If no argument is given, stack probes are treated according to the default. This pragma takes effect at the first function defined after the pragma is seen. Stack probes are neither a part of macros nor of functions that are generated inline.

If you don't give an argument for the check_stack pragma, stack checking reverts to the behavior specified on the command line. For more information, see Compiler Reference. The interaction of the #pragma check_stack and the /Gs option is summarized in the following table.
