It delivers status information from - * the Linux ISDN subsystem to user level. - * - * DATA FORMAT - * When reading from this device, the current status of the - * Linux ISDN subsystem is delivered in 6 lines of text. Each - * line starts with a tag string followed by a colon and - * whitespace. After that the status values are appended sep- - * arated by whitespace. - * - * flags is the tag of line 5. In this line for every driver - * slot, it's B-Channel status is shown. If no driver - * is registered in a slot, a ? is shown. For every - * established B-Channel of the driver, a bit is set - * in the shown value. The driver's first channel is - * mapped to bit 0, the second channel to bit 1 and so - * on. - * ------------------------------------------------------------ - * - * So we open /dev/isdninfo, discard the first four lines of text - * and then check whether we have something that is not `0' or `?' - * in one of the flags fields. - * - * Sounds complicated, but I don't see any other way to check whether - * we are connected. Also, this is the method some other ISDN tools - * for Linux use. - * - * Martin - */ - - f = fopen ("/dev/isdninfo", "r"); - - if (!f) return FALSE; - - for (i = 0; i < 5; i++) { - if (fgets (buffer, BUFSIZ, f) == NULL) { - fclose (f); - return FALSE; - } - } - - if (strncmp (buffer, "flags:", 6)) { - fclose (f); - return FALSE; - } - - p = buffer+6; - - while (*p) { - char *end = p; - - if (isspace (*p)) { - p++; - continue; - } - - for (end = p; *end && !isspace (*end); end++) - ; - - if (*end == 0) - break; - else - *end = 0; - - if (!strcmp (p, "?") || !strcmp (p, "0")) { - p = end+1; - continue; - } - - fclose (f); - - *online = TRUE; - return TRUE; - } - - fclose (f); - - *online = FALSE; - return TRUE; -} - -/* Provides PPP/ISDN information. */ - -void -glibtop_get_ppp_s (glibtop *server, glibtop_ppp *buf, unsigned short device) -{ - int in, out, online; - - glibtop_init_s (&server, GLIBTOP_SYSDEPS_PPP, 0); - - memset (buf, 0, sizeof (glibtop_ppp)); - - if (is_ISDN_on (server, &online)) { - buf->state = online ?
