Does anyone have any experience in writing TSR (Terminate & Stay Ready)
programs in either Microsoft C 5.0 or MS QuickC? Specifically, has
anyone made use of the _chain_intr, _dos_getvect, _dos_setvect and/or
_dos_keep functions?
The runtime library reference, which provides reasonably good examples
for most functions, has very little info. on these.
I'd appreciate any information about how to apply any or all of these
functions. Also, if someone has a short example handy, I'd sure like
to see the source code!
Thanks,
Jon
P.S: Please don't respond that I should use assembly language. If
I wanted to use MASM, I would, and a reader full of flames
from assembler wonks won't help me learn C, which is the
whole purpose of this exercise.

I hate to tell you this, but using these library routines can be a royal *PAIN* for someone new to C and/or the IBM PC (and even for those who aren't), primarily because of DOS reentrancy problems (i.e., a TSR can't use DOS if the foreground process is already using it). I don't want to sound like a living advertisement, but Blaise Computing offers a package called C TOOLS PLUS/5.0, which provides a number of routines to help support writing TSRs which go way beyond the MSC library routines, as well as text windows, menus, screen access, and a whole bunch of other stuff. It costs about $175, but it may save you ten times that much in headaches. It also comes with lots of example programs written in C, documentation, and source (mostly C). This package is functionally almost identical to our product Turbo C TOOLS (for Turbo C), which has a write-up in this month's Turbo Technix magazine.

The Feb. & Mar. issues of Computer Language magazine contain two articles on writing TSR's in Turbo C and MSC/QuickC respectively.
