Hi Edward,
The following code reads line by line the textual output of 'backend 6':
#include <stdio.h>
main()
{
FILE * fp;
char str[1024];
fp = popen ("/usr/lib/netman/bin/backend 6", "r");
if (fp == NULL) return -1;
fgets (str, 1024, fp);
while (!feof (fp))
{
printf ("%s", str);
fgets (str, 1024, fp);
}
pclose (fp);
return 0;
}
I will have a look at your code.
Thanks,
Aitor.
