I am trying to work this little program, its not working..
Code:
int main()
{
FILE *fp;
char *args[40];
pid_t child, exited_pid;
int status = 0;
*args[0] = "less";
fp = popen("ls", "r");
child = fork();
if(child == 0)
{
dup2(fp->fd, 0);
if(execvp(args[0], args) == -1)
{
printf("error");
exit(EXIT_FAILURE);
}
wait(&status);
wait(&status);
}
I got error.
Warning: assignment makes integer from pointer without a cast
Error: 'FILE' has no member named 'fd'
Error: expected declaration or statement at end of input.
My whole goal of the program is to execute ls, and read from that program & store it in the buffer. Then my second program (argss[0]) reads the input coming from there and uses it...
help plz
