syscall: use prlimit64, not prlimit #2492
Description
Rlimit.Cur/Max should be declared as uint, not uint64. I'm on weekly 2011-11-18
/usr/include/linux/resource.h
struct rlimit {
unsigned long rlim_cur;
unsigned long rlim_max;
};
on 386:
#include <sys/resource.h>
#include <stdio.h>
int main() {
struct rlimit rl;
getrlimit(RLIMIT_NOFILE, &rl);
printf("sz %d c %d m %d", sizeof(rl.rlim_cur), rl.rlim_cur, rl.rlim_max);
}
=>
sz 4 c 1024 m 4096
8g however,
package main
import (
"syscall"
"fmt"
"unsafe"
)
const RLIMIT_NOFILE = 7
func main() {
lim := syscall.Rlimit{}
syscall.Getrlimit(RLIMIT_NOFILE, &lim)
fmt.Printf("sz %d c %d m %d", unsafe.Sizeof(lim.Cur),
lim.Cur, lim.Max)
}
=>
sz 8 c 17592186045440 m 0
