Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version
7.0, special attention must be paid to linking a program intended to be
a "terminate-and-stay-resident" (TSR) program.
For example, a very short program with only 4K of data and about 2K of
code may result in an executable that is about 70K in size.
More Information:
The linker normally allocates all available memory to a program. You
can use the /CP switch to adjust the allocation down. If you specify
an amount less than the minimum allocation, the maximum allocation
will default to that minimum, so link with /CP:1.
You can also use the /max <MinimumAllocationInHexParagraphs> option of
the EXEMOD.EXE utility to adjust the maximum allocation of a program.
Microsoft C was not designed for writing memory resident software.
Although it is possible, you also may need to make modifications to
the start-up code. Be cautious about what functions you use and what
MS-DOS functions are called.
