Daniel,
Based on this, I think I was erroneous in suggesting that plain flags
(setflag, isflagset) are transaction-associated. They seem to be
message-associated, not transaction. Is this right?
in first place is associated to message, then inherited to transaction
(when that is created) and kept for the life of the transaction. So both
associations are true, of course, a matter of whether the transaction
was created or not at respective time.
Cheers,
Daniel

Hello,
here is a wiki page with some flag bitmask vector examples that might
help:

The cfg file examples are for older kamailio versions.
Cheers,

I'm in doubt of the means of setflag()'s parameter. I have looked for
it everywhere including internet and the ser source code, but no any
docs explained it in detail. can anybody tell me about it ?
It sets bits in a 32-bit integer (it may be 64-bit on 64-bit
platforms, of this I am not sure) that is bound to a transaction, so
those "flags" may be accessed in requests and replies associated with
a given transaction, or, further down in the execution flow of same
message handler.
It is precisely equivalent to the way bit vectors are used in
general-purpose programming languages, e.g.
int flags = 0;
flags |= (1 << 4); /* Set bit 4 */
if(flags & (1 << 4)) {
printf("Bit 4 is set!\n");
} else {
printf("Bit 4 is not set!\n");
}
/* If bit 4 is set, unset it */
if(flags & (1 << 4))
flags &= ~(1 << 4);
