POChar Pointer Segmentation Fault
text
Body
copied!<p>Okay so here is the gist of what's happening:</p> <p>I am passing in a character array <code>(char[x])</code> into a function, whose argument is defined to be a character pointer <code>(char *)</code>. Once inside the function I assign another character pointer (which is a part of a struct I have). I get a segmentation fault as soon as I assign the incoming argument, to the structure's character pointer; as such.</p> <pre><code>temp->name = (char*)malloc(sizeof(char)); temp->name = name; </code></pre> <p>This is how I've been utilizing the function previously:</p> <pre><code>char *name = "HEY"; Function(name); </code></pre> <p>Here's how I am utilizing it with errors:</p> <pre><code>char name[3] = "HEY"; Function(name); </code></pre> <p>with the same statement above, and it works fine. I made sure it wasn't anything else, by changing name to a constant "HEY", with the same input and everything went smoothly. </p> <p>If anybody can think of a reason why off the top of their head, I would greatly appreciate the help. Thank you! </p> <p><strong>Here's the function in full:</strong></p> <ul> <li>openList is the pointer to the beginning of a linked list of structs</li> <li>tempOpen is a temporary pointer we can utilize to scour through the list, without altering the openList position</li> <li>findOpenSetSID/findItem -> looks for a struct in the linked list via the SID/key</li> <li>answerOpen/answerItem -> 1 == first node, 2 == any other node, 0 = not found</li> </ul> <p><strong>Here is a breif summary of the structures involved.</strong> The open structure is a linked list of pointers to another structure (called set structures) A set structure is a linked list of names, sid's, and a item structure An item structure is a linked list of data and keys</p> <pre><code>Error_t WRITE(Sid_t sid, char *key, char *data){ Open_p_t tempOpen = openList; //setting a pointer to a struct int answerOpen = findOpenSetSID(sid, &tempOpen); if(answerOpen > 0){ Set_p_t targetNode; if(answerOpen == 1){ targetNode = tempOpen->file; } else{ targetNode= tempOpen->next->file; } Item_p_t tempItem = targetNode->items; int answerItem = findItem(key, &tempItem); Item_p_t targetItem; targetItem = (Item_p_t)malloc(sizeof(Item_t)); if(answerItem > 0){ if(answerItem == 1){ targetItem = targetNode->items; } else{ targetItem = targetNode->items->next; } targetItem->data = data; } else{ **targetItem->data = data;** <<<The problem line. basically I am just adding items to my sets. But this line freaks out when the input changes from char* to char[] targetItem->key = key; targetItem->next = targetNode->items; targetNode->items = targetItem; } return 0; } return 1; } </code></pre> <p><strong>Here's the input segment:</strong></p> <p><code>char key[32], data[64]; // reads in data using fscanf(fd, "%s %s", key data) then calls WRITE(setId, key, data);</code></p>
