Is it possible to get the corresponing memory segment and memory offset of
a variable in the program?
Thank you.

If you’re using Neutrino - the segment registers don’t mean the same thing
as in the 16-bit realmode. Everything is in a flat 32-bit addressing space
so you don’t need a segment/offset pair.
If you want to know what the virtual address of a variable is, in C - just
grab the address and save it in a pointer. Eg:
char *a = &mychar;
If you wish to know the physical location of the variable, you should check
out the documentation http://qdn.qnx.com/support/docs/neutrino/lib_ref/m/mem_offset.html
for more information.
