[patch] getrlimit.2: fix example program

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


man-pages version: latest git repository
why: Fix compile error of the example program.
Use struct rlimit instead of rlimit64, which is used in prlimit64().
Make error handling code similar with other examples.
