Body
<p>I'm trying to create a structure, that has a function pointer. That function pointer points to a function, that takes a pointer of said structure. This is a real chicken-or-the-egg problem because the prototype needs to know about the structure and the structure needs to know about the prototype. Is there a way to predefine the struct? I'm new to C so if anyone has any insight I would greatly appreciate it.</p> <p>Thanks, -devnull</p> <pre><code>#include <stdio.h> /* predefine struct person? */ void printInfo(struct person *); struct person{ char *name; int age; const void *pf = printInfo; }; int main(){ struct person master = {"Master", 23}; return 0; } void printInfo(struct person *p){ printf("Name:\t%s\n", p->name); } </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.
