Added:
isc_buffer_base(b) (pointer)
isc_buffer_current(b) (pointer)
isc_buffer_active(b) (pointer)
isc_buffer_used(b) (pointer)
isc_buffer_length(b) (int)
isc_buffer_usedlength(b) (int)
isc_buffer_consumedlength(b) (int)
isc_buffer_remaininglength(b) (int)
isc_buffer_activelength(b) (int)
isc_buffer_availablelength(b) (int)
Removed:
ISC_BUFFER_USEDCOUNT(b)
ISC_BUFFER_AVAILABLECOUNT(b)
isc_buffer_type(b)
Changed names:
isc_buffer_used(b, r) ->
isc_buffer_usedregion(b, r)
isc_buffer_available(b, r) ->
isc_buffer_available_region(b, r)
isc_buffer_consumed(b, r) ->
isc_buffer_consumedregion(b, r)
isc_buffer_active(b, r) ->
isc_buffer_activeregion(b, r)
isc_buffer_remaining(b, r) ->
isc_buffer_remainingregion(b, r)
Buffer types were removed, so the ISC_BUFFERTYPE_*
macros are no more, and the type argument to
isc_buffer_init and isc_buffer_allocate were removed.
isc_buffer_putstr is now void (instead of isc_result_t)
and requires that the caller ensure that there
is enough available buffer space for the string.
