Subject:	Global functions

       I've been combining ansi-C source with AT&T syntax assembler
source using the DJgpp compiler.  My question is this:


       How can I combine my related sources, which share many functions
between each other, into one object file with only the functions I
specify being available to the linker for use with other object files.

In other words, I have 2 functions that I want to be global for general
use:
               initialize_serial_driver(char * buffer, int length)
                                &
               string_from_com_port(char* buffer, length)

but I have other functions that must be called between the C and
assembler code that I don't want to be global after compilation.

Could someone please point me in the general direction of some info on
this or give me some assembler or C directives I should look at, maybe
some gcc or ld command line options.

Basically, what I need to do is combine some object files into one
bigger object file, and I need to be able to specify which of the
functions should be made available to the linker upon linking of this
object file.

Any and all help will be appreciated!!

                                Thanks,
                                 TomE
