I was interested in your PDPCLIB - although as it was written for OS2 a
lot more work would be required to write a version for DOS.

As a first step I ran the performance tests using perf*.c and got the
following results:

                fgets on text files
                -------------------
                
Executing - perf2
pcc time     38.51 seconds
bcc time     25.71 seconds

                large freads on binary files
                ----------------------------
                
Executing - perf3
pcc time      4.23 seconds
bcc time     22.41 seconds


                small freads on binary files
                ----------------------------

Executing - perf4
pcc time      5.60 seconds
bcc time     24.94 seconds


I used a 386DX40 with a RAM disk running under DOS 6.2

bcc = Borland C++ 3.1
pcc = Pacific C Compiler for MSDOS v7.44

Apart from the poor results for fgets on text, Pacific compares
favourably (with Borland). I am at a loss to explain this - even though
it only uses a 1024 char buffer this should not make that much
difference.

I will try adapting some of the PDPCLIB code. Would you consider including
typedefs for user defined types ULONG etc are obvious, but APIRET? I
assume these are in OS2.h?
