RE: stupid question

[CAVEY GERARD <GERARD CAVEY sgam com>]

thanks a lot for ur answer

i thought doing it long time ago
thus i need high perfomance
and i would prefer to avoid using hard drive access
if it is possible :D
i also thought about storing it in env variable (   system("tmp_var=`grep
Page MyDoc|wc -l`") and then use
myvar=atoi(getenv(tmp_var)); to access command result
but i guess there should be a more simple solution and more effective
anyway thanks for ur answer amigo :)

any other suggestion ??

You can use the popen system call:
FILE *shell_fd;
char cabecera[80];

shell_fd = popen ("grep Page MyDoc|wc -l", "r");

  if ((shell_fd == (FILE *) NULL) || (shell_fd == (FILE *) - 1))
    return;

  while (fgets (cabecera, 80, shell_fd) != NULL)
    {
       printf("%s\n",cabecera);

    }
