I just discovered that
outb (0x250, *c++); /* doesn't work whereas */
outb (0x250, *c); c++; /* works */
I would guess (but cannot verify) that
*c++ = inb (0x250); /* probably works since the increment expression is
* not part of the macro */
can somebody verify this for me I am pretty sure about the inb (even
though I can't test it easily), as for the outb since outb just is a macro
that puts in an inline function outbv() why does it not work?
