Not necessarily, but certainly a new library. I only meant that there
was a single public function which was called with an object that
contained the information about how the logging was actually being
accomplished. I'm just saying make your API mostly private and create a
log baton that contains the details.

Something like this:

typedef struct svn_log_baton_t
   svn_repos_t *repos;
   svn_repos_loglevel_t loglevel;
   svn_stream_t **errlogfile;
   svn_stream_t **accesslogfile;
   /* other elements as seem useful */
} svn_log_baton_t;

Then your calls to svn_repos_write_accesslog() et al swap the
svn_repos_t for a svn_log_baton_t. All of the calls to
svn_repos_[get|set]_[error|access]log then become private to log library.
