相关函数

#include <unistd.h>int gethostname(char *name, size_t name);#include <sys/utsname.h>int uname(struct utsname *name);

相关结构

struct utsname{char sysname[];char nodename[];char release[];char version[];char machine[];}

例子

int main(void){        char computer[256];        struct utsname uts;        if (gethostname(computer, 255) != 0 ||  uname(&uts) != 0) {                fprintf(stderr, "can not get host information\n");                return 1;        }        printf("host name: %s\n", computer);        printf("system name: %s\n", uts.sysname);        printf("hardware : %s\n", uts.machine);        printf("nodename : %s\n", uts.nodename);        printf("release: %s\n", uts.release);        printf("version: %s\n", uts.version);        return 0;}
