關(guān)于setrlimit的問題～

iw1210

在程序中先用了getrlimit，然后用 setrlimit 設(shè)置，然后再用 getrlimit 查看設(shè)置成功。為什么再運(yùn)行一個這個程序的實(shí)例，執(zhí)行第一個getrlimit后，發(fā)現(xiàn)前面那個實(shí)例的設(shè)置在這個實(shí)例無效？

man setrlimit


NOTES
       A child process created via fork(2) inherits its parent's resource limits.  Resource limits are preserved across execve(2).

       One can set the resource limits of the shell using the built-in ulimit command (limit in csh(1)).  The shell's resource limits are inherited
       by the processes that it creates to execute commands.
