In practice, we sometimes need to use the C language to invoke the 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 result in the results string arrayParameter: cmd indicates the command to execute//result is the result of the execution of the stored string array//function executed successfully returned 1, failed to return 0int Execmd (char* cmd,char* result) { Char buffer[128]; Defining buffers file* pipe = _popen (cmd, "R"); Open the pipeline and execute the command if (!pipe) return 0; Returning 0 indicates a failed run while (!feof (pipe)) { if (fgets (buffer, $, pipe)) { Output pipe to result strcat (Result,buffer); } } _pclose (pipe); Close pipe return 1; Returning 1 indicates a 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 see: http://msdn.microsoft.com/en-us/library/96ayss4b (v=vs.80). aspx.
