Is it safe to call setrlimit(RLIMIT_NOFILE, ..) from a library?
The code does
if (getrlimit(RLIMIT_NOFILE, &rl) == 0) {
rl.rlim_cur = rl.rlim_max;
(void) setrlimit(RLIMIT_NOFILE, &rl);
}
No. Libraries should not have side effects like this.
Erm... depends on the type of library. libshell (which is ksh93 provided
as a shell) can generate such side-effects if someone uses the "ulimit"
builtin command.
If you invoke a "ulimit" command, then changing RLIMITs is not a
side-effect. Instead it's the main intended result. Cases with
side-effects are different, IMHO at least.
Hugh.
PS: Provided libshell only changes the intended limit, of course.
