Body
<p>here's an alternative test code that works fine, take a loot at it and see if it helps. in addition, you can add </p> <pre><code>typedef struct node_t { struct node_t* next; char* value; } node; </code></pre> <p>this may appear simpler to understand, but it isn't because nature of typedef is confusing. I STRONGLY suggest you take a look at <a href="https://github.com/torvalds/linux/blob/master/Documentation/CodingStyle" rel="nofollow">https://github.com/torvalds/linux/blob/master/Documentation/CodingStyle</a> This is the coding style of the linux kernel, it is very short and simple, not particularly a law, but it is worth noting...</p> <pre><code>#include <stdio.h> #include <stdlib.h> #include <string.h> struct node_t { struct node_t* next; char* value; }; struct node_t* create(const char* istr) { struct node_t* ptr = (struct node_t*)malloc(sizeof(struct node_t)); char* tmp = (char*)malloc(sizeof(char) * (strlen(istr) + 1)); strcpy(tmp, istr); ptr->next = 0; ptr->value = tmp; return ptr; } struct node_t* remove(struct node_t* start, const char* value) { struct node_t* current = start; struct node_t* prev = start; while (current != 0) { if (!strcmp(value, current->value)) { if (current == start) { struct node_t* retval = current->next; free(current->value); free(current); return retval; } else { /* nothing happens */ return 0; } } } } int main(const int argc, const char** argv) { struct node_t* pt = create("1"); printf("%s\n", pt->value); pt->next = create("2"); printf("%s\n", pt->next->value); remove(pt, "1"); return 0; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
