Doubly Linked List???

I'm trying to make a doublly linked list then uses an addbefore and addafter function the return a pointer to a node. It works when I don't use the function but messes up when I use them





Here is my code some of my code





void insert(ListNodePtr *sPtr, char *string){


some code...( *sPtr is my main node)


.


.


.


while(currentPtr-%26gt;prevPtr != NULL %26amp;%26amp; (strcmp(string, currentPtr-%26gt;word) %26lt;= 0)){


currentPtr = currentPtr-%26gt;prevPtr;


}


*sPtr = addAfter(currentPtr, string); //ADDING AFTER


}


.


.


.


}

The part of insert() that you quoted doesn't initialize currentPtr, but maybe that gets done in the elided section. Presumably you want to set currentPtr = sPtr.





In addAfter(), I assume you want to copy the passed string into the new node, but that doesn't appear to happen, unless it's buried in the part that Yahoo turned into "...".
