Also, I trust that you know what you're doing! Depending on the
implementation of C++, a pointer to a function can sometimes be a pointer to a
function descriptor. So be careful with what you do with opts_char. (But you
say that the resulting code basically works so that is good.)
Also, on USS
ahk> cat cm.C
extern "OS" typedef int mytype(void *);
extern mytype M;
void p()
{
char *x;
x = reinterpret_cast<char *>(M);
}
ahk> xlC -c cm.C
"./cm.C", line 8.33: CCN5216 (W) An expression of type "extern "OS" int
(*)(void *)" cannot be converted to type "char *".
ahk> xlC -c -qsuppress=CCN5216 cm.C
