assistant: Hi Bill,
You wrote to Roger Scudder,
[Re - Ray Duncan's "Advanced MSDOS"]
It does cover memory allocation, it is very poor on disk stuff beyond
the normal.
and
It covers all _documented_ MSDOS functions. It lists as "Reserved", or
just plain omits, quite a few useful MSDOS functions (some essential for
TSRs) which MS/IBM didn't want other programmers to use for various
reasons - see "Undocumented DOS" by Andrew Schulman et al. Remember
"Advanced MSDOS" was published by Microsoft Press...
The way MSDOS uses interrupts comes from the way the 80x86 family of
processors is designed, and in my opinion is valid for the hardware it
is designed to run on. I made similar use of interrupts (accessing
comonly used functions) to cut down code size on a memory constrained
8085 system.
Why use a USART? I've never needed synchronous communications links yet.
I agree that it's useful, especially as there are no major extensions to
the MS/PCDOS interface since DOS 3.3, but it certainly isn't complete. I
bought two other useful books at the time (6-7 years ago) to get a
better overview. "DOS Programmer's Reference" by Terry R. Dettmenn is
much more heavily thumbed than Duncan's book, most sample code in C. The
other book was "Undocumented DOS": see above. The most complete
information on MS/PC/DR DOS interrupts is in the INTRLIST maintained by
Ralf Brown.

assistant: /*
  I think you're assigning null to a pointer that is already de-referenced.
  If you want to null out the pointer, I suggest you remove the
e-referencing
  asterisk.
*/
I don't know of a single function that can do it, but some standard functions
can be used to check it:
  i = 0;
  while(!isdigit(sTemp[i]) && (sTemp[i] != '-'))
  {
    if (!isspace(sTemp[i]))
      /* notify of bad input, and possibly remove from string */
    i++;
  }
  if (sTemp[i] == '-')
    i++;
  while(i < len(sTemp))
  {
    if (!isdigit(STemp[i]))
      /* more bad input to be removed */
    i++;
  }
atoi() is supposed to stop as soon as it hits a bad character.

assistant: Hmmm... I don't know of a mixed-language echo yet, so I guess I'll post this
here.
I'm not certain I'd call it easy, but it can be done.  In a pascal file,
ou'd
need to use a {$L ...}
C (and most extensions/expansions thereof) require a "main" function to start
the program.  Both languages can share functions/procedures, but I'm not sure
about variables.  Also remember that the C compiler will add an underline to
the beginning of each identifier used within the program.  If the C routines
use any standard functions, you may also have to tell turbo pascal to link
he
library file.

Discussions about interrupts and the like are not off-topic for the C_Echo
per se, provided some sort of relevancy to C programming can be maintained.
Discussions about how X or Y system architecture manages to schedule
interrupt priorities etc. may be of general interest to C programmers, for
example if it helps them to bullet-proof their code or better understand how
it may be executed. However, the moment this thread outlives its usefulness
in that aspect, it would seem appropriate to terminate it or move it to a
more suitable discussion forum. For the time being, I'll leave it upto the
participants themselves to determine when that moment has come.
Fair enough?

This sounds like DOS so I'll assume that for this reply...
It can probably be solved easily and more reliably by some DOS IOCTL call or
so (have a look in Ralf Brown's Interrupt List) or by intercepting some error
handler (same source for information), but in a program I once wrote I asked
INT 11h how many physical floppy drives there were and this worked for me,
back then.
In that same program I read out the floppy drive types from the CMOS (at
least if it had one), used DOS IOCTL calls to discover any network drives and
removable devices etc. and asked MSCDEX for CD-ROM drives. What was left I
assumed being a local fixed disk.

Just wished to inform that Zoltan (Ladysmith, BC, Canada) is now wired into
the International C Echo.
I am currently experiencing some technical difficulties but hope to resolve
them very soon and then get on with the business at hand.  I was hoping that
I could employ this echo to as a guideline to build code as it pertains to
digital communication and thus post bits of code for the rest of you to rip
apart.  <G>
My real life experience is with Fortran and C (Unix enviroment) as it
pertains to geophysical signal analysis and thus when I began to program more
for my own amusement I discovered that I enjoyed programming comport routines
and the such since I really like to babble.  :)
I hope that this ideology has found a home here.
Thanks for listening,
Maurice

 It does not go it lowlevel disk opps that much, just int 25h and 26h.  It

 It certainly covers memory, allocation, compleat with the asm on how to
