HELP liblber API
HELP! I'm stuck.
Is there a doc about the API for liblber? I have a TCP socket
sock. I want to read BER-encoded data from it. How can I do it? The man
Normally, the only routines that need be called by an
application are ber_get_next() to get the next BER element
and ber_scanf() to do the actual decoding. In some cases,
ber_peek_tag() may also need to be called in normal usage.
The other routines are provided for those applications
that need more control than ber_scanf() provides. In gen-
eral, these routines return the tag of the element
decoded, or -1 if an error occurred.
The ber_get_next() routine is used to read the next BER
element from the given Sockbuf, sb. A Sockbuf consists of
the descriptor (usually socket, but a file descriptor
works just as well) from which to read, and a BerElement
structure used to maintain a buffer. On the first call,
the sb_ber struct should be zeroed. It strips off and
returns the leading tag byte, strips off and returns the
length of the entire element in len, and sets up ber for
subsequent calls to ber_scanf() et al to decode the ele-
Okay, so that are the steps I need to make? I'm trying:
ber_tag_t tag, berlen;
psockbuf = ber_sockbuf_alloc_fd(sock);
memset(&ber, '\0', sizeof(BerElement));
tag = ber_get_next(psockbuf, &berlen, &ber);
And I get a segfault and an assertion:
listen: io.c:492: ber_get_next: Assertion `(( ber
What am I missing?
The man page seems broken anyway, there is no BerElement in a
