New Revision: 1094152
URL: http://svn.apache.org/viewvc?rev=1094152&view=rev
Log:
Add a simple API function that allows you to read the current
serialization buffer usage. Since we always append, one can
determine the size of appended data by diff'ing the sizes
before and after the respective sub-structure got serialized.
* subversion/include/private/svn_temp_serializer.h
(svn_temp_serializer__get_length): declare new API function
* subversion/libsvn_subr/svn_temp_serializer.c
(svn_temp_serializer__get_length): implement it
