Then you need to read the files in /proc/<pid>/*. There isn't a system
call to get resource usage for another process.
Note that you won't be able to determine how much of the allocated
heap is free or used; that information is internal to the process, and
isn't visible externally.
thanks. Infact, I used /proc/<pid>/statm to find out total size, RSS and
shared memory from 1st 3 entries. Don't know about the accuracy or not
but that will do. But, this file does not tell about max. heap consumed
by a process nor does /proc/pid/status and I am not able to decipher
/proc/pid/stat. Does anyone knows how to interpret stat file?
