在c语言里怎么调用linux命令
如下：#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
int main(void)
{
printf("real uid=%d, effective uid=%d\n",getuid(),geteuid());
exit(0);
user_id_t uid;
uid=geteuid();
setuid(uid);
//我想在这里调用linux的setup命令
return 0;
} system function
The system function is used to issue a command. Execution of your program will not continue until the command has completed.
Library: stdlib.h
Prototype: int system(const char *cmd);
Syntax: system( "cat /etc/hosts");
Notes:
In Unix systems, the command is passed to "/bin/sh -c" for
execution. I do not know what handles the command in DOS systems.
