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.

Hi Aitor,
The best way for you is to use the backend's code for reference. What
you want is already implemented there. TProcesss was used to trap the
background cli commands output although there are instances where that
output is discarded.
What you need is this from the CLI backend's code (core_functions.c):
[ code snippet from getDefaultDevices() ]
FILE * shell_reader;
char scan_buffer[1024];
[...]
shell_reader = popen(command, "r");
if(!shell_reader) {
fprintf(
stderr,
"ERROR: getDefaultDevices(): "
"popen() failed (Error: %s)\n",
strerror(errno)
);
return -1;
}
char* ptr;
while((fgets(scan_buffer, 1024, shell_reader))) {
ptr = (char*) scan_buffer;
if (strstr((char *) scan_buffer, "lo") == ptr)
continue;
else if (strstr((char *) scan_buffer, "wl") == ptr) {
snprintf(
_wl,
1024,
"%s",
(char*) scan_buffer
);
} else if (
strstr((char *) scan_buffer, "eth") == ptr ||
strstr((char *) scan_buffer, "en") == ptr
) {
snprintf(
_eth,
1024,
"%s",
(char*) scan_buffer
);
}
}
pclose(shell_reader);
Ask again if you in the event you may need more help.
