这是msdn的解释

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 not 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 Table 2.1.

#pragma check_stack + Yes or no Turns on stack checking for functions that follow
#pragma check_stack(off) or

你可以查MSDN,上边有很详细的解释,一般是#pragma...用来改变编译器的默认行为
