Getting all output from terminal in C

Question

I am currently working on a ssh program and I want to be able to have full control over the terminal via networking. My question is, if I send a command to the server to run in

You want the "popen" function. Here's an example of running the command ls /etc and outputting to the console.

#include 
#include 


int main( int argc, char *argv[] )
{

  FILE *fp;
  int status;
  char path[1035];

  /* Open the command for reading. */
  fp = popen("/bin/ls /etc/", "r");
  if (fp == NULL) {
    printf("Failed to run command\n" );
    exit;
  }

  /* Read the output a line at a time - output it. */
  while (fgets(path, sizeof(path), fp) != NULL) {
    printf("%s", path);
  }

  /* close */
  pclose(fp);

  return 0;
}
