an `inline int opt_finished` causes GCC to spew this error when used
with -std=gnu99:
libcoap/option.c:165: undefined reference to `opt_finished'
Signed-off-by: Olaf Bergmann <bergmann@tzi.org>
The iterator object now distinguishes between "not filtered" (using
COAP_OPT_ALL which is now set to NULL) and an explicit filter. When
filtering is used, only options between 0 and COAP_MAX_OPT can be
filtered from the option set. Use COAP_OPT_ALL for anything beyond
COAP_MAX_OPT.
Removed any occurrence of option jumps from coap-12,
option iterator:
- bad bit to track iterator status
- option now points to the next field, the current
option is delivered by coap_options_next()
The subdirectory "tests" now contains a growing set of unit tests for the
libcoap API. To use this, you will need CUnit (see http://cunit.sourceforge.net)
and must configure with the option --with-tests.
