Is there a library call or syscall to set /proc/self/oom_score_adj?

Question

I have an important process that the OOM Killer has taken a fancy to with unfortunate results. I would like to make this less likely. All google turns up is stuff like:

echo -1000 > /proc/${PID}/oom_score_adj

while I would like to do it in the program source itself. Is there a library call or syscall to do this, or is my only option getpid(), open(), write() & close() ?

Answer 1

There’s no system call, or library function, as far as I’m aware. No need for getpid() though, you can open /proc/self/oom_score_adj directly.
