I just checked in support for string buffers to emem.[ch], which are growable
strings similar to GStrings. You can use them to do things like the following:
emem_strbuf_t *strbuf;
strbuf = ep_strbuf_new_label("Flags: ");
ep_strbuf_printf_append(strbuf, "%s (%04x)", "lemons", 2);
ep_strbuf_printf_append(strbuf, ", %s (%04x)", "marmots", 32);
proto_tree_add_uint_format(tcp_tree, hf_fruits_mammals, tvb, offset, 2,
flags, "%s (%04x)", strbuf->str, flags);
More information can be found in README.malloc and emem.h.
