i am trying to compile the following with gcc on a RH 9.0 box:

#include <sys/types.h>
#include <sys/resource.h>
#include <sys/time.h>
#include <unistd.h>
#include <stdio.h>

/* resource.c */

int main(int argc,char* argv[]){
    struct rusage r_usage;
    struct rlimit r_limit;
    getrusage(RUSAGE_SELF, &r_usage);
    printf("User: %ld.%06ld\n",r_usage.ru_utime.tv_sec,
                               r_usage.ru_utime.tv_usec);
    getrlimit(RLIMIT_FSIZE,&r_limit);
    printf("Current FSIZE limit: soft = %ld, hard = %ld\n",
           r_limit.rlim_cur,r_limit.rlim_max);
    return 0;
}

with:

gcc -o resource resource.c

but it came back with the error that says 'struct rusage r_usage' is
undeclared (it also complain about 'struct rlimit'). i am sure that i
have missed something so gcc is not able to find the definition of the
rusage strrct but since this is the first time i am trying to program
in linux, i don't know how to solve that. i have googled around for a
while with no avil. can someone tell me what's wrong? thanks!
