SUMMARY
With the Microsoft C compiler, the choice to use the /F compiler
option or the /STACK linker option to specify a stack size for a program
depends on the method being used to compile and link.
MORE INFORMATION
If you using the CL command to compile and link, the /F compiler
option is all that is necessary. This option will pass the correct
size of the stack to the linker.
Conversely, if you are invoking the compiler and the linker separately
(as in a MAKE file), the /STACK link option can be used to get the
desired stack size.
No stack information is stored in the object module. Therefore, using
the /F and /c (compile only) options together and then invoking link
separately will not generate the desired stack size.
For OS/2, Windows, Windows NT, and Windows 95 applications, the stack size
can be specified in the .DEF file using the STACKSIZE directive. STACKSIZE
overrides the size specified on the link line.
For 16-bit linkers, the default stack size is 2K. If an odd value is
specified for the stack size, the linker will round it up to the next even
value. For 32-bit linkers, the default stack size is 1MB. The linker
rounds up the specified value to the nearest 4 bytes.
