How can I get the Length of the Call Reference value??
I have found this at the libpri-1.2.3 sources:
q931.c ine 2260
pri_message(pri, "%c Protocol Discriminator: %s (%d) len=%d\n", c, disc2str(h->pd), h->pd, len);
pri_message(pri, "%c Call Ref: len=%2d (reference %d/0x%X) (%s)\n", c, h->crlen, q931_cr(h) & 0x7FFF, ..............
line 2040
static inline int q931_cr(q931_h *h) {
int cr = 0; int x;
if (h->crlen > 3) {
pri_error(NULL, "Call Reference Length Too long: %d\n", h->crlen);
return -1;
}
switch (h->crlen) {
case 2: for (x=0;x<h->crlen;x++) { cr <<= 8; cr |= h->crv[x]; }
break;
case 1: cr = h->crv[0]; if (cr & 0x80) { cr &= ~0x80; cr |= 0x8000; }
break;
default: pri_error(NULL, "Call Reference Length not supported: %d\n", h->crlen);
}
return cr; }
My problem is, how can I get h->crlen in a variable so I can use it in the extensions.conf
