Calling Convention

This section describes the process that one function (caller) makes call into another function (callee).

For prototyped functions, all arguments are converted to the expected callee types before passing.

• Parameter Passing

• Varargs

• Unprototyped Functions

• Return Values

• Caller/Callee Saved Registers

• Function Pointers

• Floating-Point Support for Older Code (Visual C++)

• FpCsr

• MXCSR

• setjmp/longjump
