测试kernel.pid_max值

# sysctl kernel.pid_max
kernel.pid_max =
# sysctl -
kernel.pid_max =   

#include <unistd.h>
#include <stdio.h>
int main ()
{
    pid_t fpid; //fpid表示fork函数返回的值
    ;
    ) {
        fpid=fork();
        ) {
            printf("error in fork!\n");
            break;

        return ;
        }
    }
    printf("count is %d\n", count);
    return ;
}

# gcc test.c; ./a.out
error in fork!
count is
