check_stack pragma
Instructs the compiler to turn off stack probes if off (or -) is specified, or to turn on stack probes if on (or +) is specified.
Syntax
#pragma check_stack([{on|off}])
#pragma check_stack{+|-}
Remarks
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 options. The interaction of the #pragma check_stack and the /Gs option is summarized in the following table.
