This syntax (in ghost.c) probably doesn't do what you think:

Code:

            if(4.70 <= data <= 5.00){

You probably mean this:

Code:

            if (4.70 <= data && data <= 5.00) {

This list handling code is incorrect:

Code:

void removeEvidenceNode(EvidenceLinkedList* list, EvidenceNodeType* node){
    if(node != NULL){
        EvidenceNodeType* prev = node->prev;
        EvidenceNodeType* next = node->next;
 
        if(prev == NULL)
            list->head = node->next;
 
        if(next == NULL)
            list->tail = node->prev;
 
        if(next != NULL && prev != NULL) {
            prev->next = next;
            next->prev = prev;
        }
    }
}

It should be more like this:

Code:

void removeEvidenceNode(EvidenceLinkedList* list, EvidenceNodeType* node){
    if(node != NULL){
        EvidenceNodeType* prev = node->prev;
        EvidenceNodeType* next = node->next;
 
        if(prev == NULL)
            list->head = next;
        else
            prev->next = next;
 
        if(next == NULL)
            list->tail = prev;
        else
            next->prev = prev;
    }
}
