function
#pragma function( function1 [, function2, ...] )
Specifies that calls to functions specified in the pragma’s argument list be generated. If you use the intrinsic pragma (or /Oi) to tell the compiler to generate intrinsic functions (intrinsic functions are generated as inline code, not as function calls), you can use the function pragma to explicitly force a function call. Once a function pragma is seen, it takes effect at the first function definition containing a specified intrinsic function. The effect continues to the end of the source file or to the appearance of an intrinsic pragma specifying the same intrinsic function. The function pragma can be used only outside of a function—at the global level.
For lists of the functions that have intrinsic forms, see #pragma intrinsic,
