[Freeswitch-users] mod_managed switch_xml_open_cfg and SIGSEGV

[Anthony Minessale]

I dont use managed stuff but in c you would have

switch_xml_t xml, cfg;

 xml = switch_xml_open_cfg("freeswitch.conf", &cfg, NULL);

cfg is the same type of xml a node inside the xml pointed in "xml"

it always returns the whole root and then the area you are searching for.

When you are done you release the xml pointer and the cfg will also be released.
