freeing up memory after sending response

[Subra Aswathanarayanan <as...@gmail.com>]

Hello,

I have a webservice in which I allocate memory for a variable and then use
that variable in creating a soap response like this

        objType_om_ele = axiom_element_create(env, response_node,
OBJECT_TYPE, ns, &objType_om_node);
        axiom_element_set_text(objType_om_ele, env, objectType,
objType_om_node);


here the variable "objectType" was malloc'd using AXIS2_MALLOC function.

in the end i return response_node and the client receives the soap response.

my question is, when should i free the memory that i allocated. i dont think
i can free it before i return "response_node" and i cant free it after the
return statement either.

your help is much appreciated!

Subra

Are you talking about freeing "objectType"? If that's the case, you can free
it just after setting "axiom_element_set_text" (before returning
"response_node").
