\S{32cfunc} Function Definitions and Function Calls
\I{functions, C calling convention}The \i{C calling convention}The C
calling convention in 32-bit programs is as follows. In the
following description, the words \e{caller} and \e{callee} are used
to denote the function doing the calling and the function which gets
called.
