Is there a system call or library function which a process can use to
determine the start of its data segment . I need to know the start of
the data segment so that process does not cross its DATA limit. Using
this information & sbrk it knows how much data space is already used &
how much it can grow further without crossing the limit.
Thanks

I think getrlimit() might be what you are looking for.

getrlimit is useful to know the limit set of a resource by setrlimit.
But I am interested in getting the start of DATA segment

The program's DATA segment is of fixed size as link time. It contains
all of the initialized variables your program has. It does not grow at
runtime. You can find out how large it is by looking at the output of
objdump. Maybe you meant to ask what is the upper limit on the size of
your heap?
