[Freeswitch-svn] [commit] r4329 - in freeswitch/trunk/src: . include

[Freeswitch SVN]

Author: mikej
Date: Mon Feb 19 17:57:27 2007
New Revision: 4329

Modified:
   freeswitch/trunk/src/include/switch_channel.h
   freeswitch/trunk/src/switch_channel.c

Log:
switch_channel_set_variable_nodup which does not dup the value from the session pool.  The value MUST already be allocated from the pool for that session, or very bad things could happen.  Use with caution.
