Hi all!
I'm trying to write a small program which probably has been written
a million times before... - A memory list showing TSRs, hooked vectors etc.
I'm not interested in simply getting a program that can do it (I got
lots of them) but in how it's done.
^^^
I've located the first MCB and found its PSP. But there's no pointer
to th next MCB which I presume I need to get and follow repeatedly until I
reach the end of the chain. Is this correct?. Some of the information I need
is in the PSP associated with each MCB, other is in the MCB itself.
HOW IS THIS DONE ???
If it has any relevance, I'm using PCDOS 3.30 and Turbo Pascal 6.0
for the experiments... The used format of a MCB and a PSP is taken from Ralf
Browns Interrupt List...
LOTS and LOTS of thanks in advance!!!!!!
Per.
PS: Source code for such a utility, in C, Pascal or commented assembler will
also do.

(Better look again; it should tell you that the MCB stores only the *length* of the allocated memory block, not a pointer to the next. It is up to you to dot the i's and cross the t's...) {text deleted} >PS: Source code for such a utility, in C, Pascal or commented assembler will > also do. Source is available for the MARK/RELEASE package from Turbo Power Software. Look for something like TSRSRC29.ARC -- (Another fine mess brought to you by valley@gsbsun.uchicago.edu)

Lovecraft - | There are several good packages worth looking at in the SIMTEL archives, the ones I would most recommend are Tesseract (you have your choice of language there) and Turbo Power's Mark/Release/Mapmem package. All are in the <MSDOS.SYSUTL> directory: TESS-5.ARC (TP5.0), TESS-C.ARC, (C), TESS-D.ARC (Docs) for Tesseract TSRSRC29.ARC for TurboPower sources (need TPAS5 & TASM) Hope this helps as a start.
