Is there a need to fix this (possible scoping problem)?

Hi Everyone,

I have a linked list I'm working on to keep track of worker nodes
(worker nodes are a client that handles requests for a server).

typedef struct Node
{
....
    char* address;  //!< address of worker
    struct Node* next; //!< Next Node
    struct Node* prev; //!< Previous Node
} Node;

Node * gTopNode = NULL;

I have a section of code that looks to me like it may contain an
error.

Given the following function (trimmed for brevity ...)

///Create a new node and add it to the end of the list
Node* CreateNode(char* address,Node* pTopNode)
{
....
    Node* pNode = NodeListFindNode(address,pTopNode);
    if(pNode == NULL)
    {
        pNode = (Node*) calloc (1,sizeof(Node));
        pNode->address = address;
        ....
    }
   .....
}

It is called as follows.



int module_init(int argc, char* argv[])
{
....
gTopNode = NodeListCreateNode("127.0.0.1",gTopNode);
....
   if(gTopNode != NULL)
       return OK;
   else
       return MODULE_FAILED
}

So my question is what will happen to gTopNode->address after
module_init returns.

A lot of places will reference it since it's a global starting point.
Will the value of address still be "127.0.0.1" or will it end up
deallocated?

Thanks in advance!
