New Revision: 87723
URL: http://svn.digium.com/view/asterisk?view=rev&rev=87723
Log:
Implement part of the stringfield modifications suggested
on the -dev list, namely:
+ new api ast_string_field_free_memory replaces
the previous ast_string_field_free_all() and
ast_string_field_free_pools()
+ remove ast_string_field_free(), use ast_string_field_set()
with a NULL argument. Fix the function to handle a NULL;
+ leave ast_string_field_free_all() defined for the time being,
as there is one place (in chan_sip.c) where it is actually
used properly, to cleanup an ast_threadstorage object across calls.
This will need further work however, because a side effect of this
usage pattern is that it will effectively leak memory
