The C language uses the cmd command and gets the output method

Go from Http://blog.csdn.net/hxh129/article/details/8000205C language use cmd command and get output method in practice, we sometimes need to use C language to invoke cmd command, and get the result of execution, Here is a simple example.   #include <stdio.h> //Description: The Execmd function executes the command and stores the results in the result string array  //parameter: cmd indicates the command to execute// Result is an array of execution results stored in the string//function execution successfully returned 1, failed to return 0  int execmd (char* cmd,char* result) {    char BUFFER[128];                          //Defining Buffers                             file* pipe = _ Popen (cmd, "R");            //Open the pipe and execute the command      if (!pipe)           return 0;                       //Return 0 indicates a run failure              while (!feof (pipe)) {     if (fgets (buffer, $, pipe)) {             //pipe output to result               strcat (Result,buffer);        }    }     _pclose (pipe);                             //closing the pipe      return 1;                                  //return 1 indicates successful run  }  int main () {    char result[1024*4]= "";                    //defines a string array that holds the result      if (1==execmd ( "ipconfig", result) {        printf (result);     }     system ("pause");                           //pause to view results  }   In addition, Microsoft's MSDN documentation has more detailed instructions, interested friends can look at:/http MSDN.MICROSOFT.COM/EN-US/LIBRARY/96AYSS4B (v=vs.80). aspx.
