_CIsin

Calculates the sine of the top value in the floating-point stack.

Syntax

void __cdecl _CIsin();

Remarks

This intrinsic version of the sin function has a specialized calling convention that the compiler understands. It speeds up the execution because it prevents copies from being generated and helps with register allocation.

The resulting value is pushed onto the top of the floating-point stack.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.

Requirements

Platform: x86
