Hi Any & All,

I recently received a request to write some code which required DMA,
however, try as I might I can't find a programmers reference for it.

So if you have a biginners guide or can point to a suitable ftp site
I would be very grateful.

Many Thanks,
TTFN Fraz

Section 3.3.3.2 in the ANSI Classic edition of the standard, so that would
be section 6.3.3.2 in the ISO edition.  Declare a pointer of an appropriate
type, assign to the pointer so that it points to the memory you want to
access, and use the unary * operator to access the memory.

Library routines strcpy() and memcpy() might also be convenient.  They're
in the index to the standard.

A program in conformance will not tend to stay in conformance, because even if
it doesn't change, the standard will.       Force = program size * destruction.
Every technical corrigendum is met by an equally troublesome new defect report.
