explain_getrlimit_or_die - get resource limits and report errors

#include <libexplain/getrlimit.h>

void explain_getrlimit_or_die(int resource, struct rlimit *rlim);

The explain_getrlimit_or_die function is used to call the getrlimit(2) system call. On failure an explanation will be printed to stderr, obtained from explain_getrlimit(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_getrlimit_or_die(resource, rlim);
The resource, exactly as to be passed to the getrlimit(2) system call.
The rlim, exactly as to be passed to the getrlimit(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

getrlimit(2)
get resource limits
explain_getrlimit(3)
explain getrlimit(2) errors
exit(2)
terminate the calling process
