Compiler Warning (level 1) C4167

function : only available as an intrinsic function

The #pragma function tries to force the compiler to use a conventional call to a function that must be used in intrinsic form. The pragma is ignored.

To avoid this warning, remove the #pragma function.

Example

// C4167.cpp
// compile with: /W1
#include <malloc.h>
#pragma function(_alloca )   // C4167: _alloca() is intrinsic only
int main(){}
