* How to determine the start of DATA segment @ 2006-03-30 16:37 Ram Gupta 2006-03-30 16:52 ` Jon DeVree 2006-03-30 17:31 ` Phillip Susi 0 siblings, 2 replies; 4+ messages in thread From: Ram Gupta @ 2006-03-30 16:37 UTC (permalink / raw) To: linux mailing-list 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.

I think getrlimit() might be what you are looking for. -- Jon "RISC architecture is gonna change everything." -Kate Libby [-- Attachment #2: Digital signature --] [-- Type: application/pgp-signature, Size: 191 bytes --] ^ permalink raw reply [flat|nested] 4+ messages in thread

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?
