Hi I need to retrieve memory usage for a running process, the last biggest size before it finishes. Top only shows the current size, and to get the last one, I need to keep watching, and if it is a long running process, that's hard to get its last biggest size. I was advised to use getrusage, it gives me the time usage correct, however the memory usage (physical and virtual) are always zero I found that linux keep process info in /proc/pid/mem or something like that, but I have to be admin to read this folder, is there a way using the process id, to get its size in memory before I cleanup and free the memory allocated?! That is in ansi C, I appreciate your help a lot, -- Kind Regards, Manal Helal
