If you have problems with memory management in C,
you can use tvb_memdup() (which automagiclly allocates buffer)
assuming prototype: FOO *yourFunc(const BYTE *ptr, unsigned int len)
you can call:
{
guint plen;
void *ptr;
FOO *bar;
plen = tvb_length(tvb); /* packet len */
ptr = tvb_memdup(tvb, 0, plen); /* buffer */
bar = yourFunc((const BYTE *) ptr, plen);
/* do what you want with bar */
g_free(ptr); /* free memory */
}
(and wireshark API has got also ep_tvb_memdup(), where you don't care
about freeing memory)
and that's all, hth!
