I have a function (populate_edit_form) declared in a header as such:
/* recmanip.h */
#ifndef RECMANIP_H
#define RECMANIP_H
#include <ncurses.h>
#include <form.h>
#include <string.h>
#include "winmanip.h"
#include "dhandler.h"
#include "sqlite.h"
#define NFIELDS 31
#define FORM_WIDTH 30
#define FORM_STARTY 2
#define FORM_STARTX 1
#define CAPTION_WIDTH 15
struct form {
const char title[15];
char value[30];
};
int add_record(void);
int populate_edit_form(FIELD *field[NFIELDS], FORM *, WINDOW *);
int print_in_middle(WINDOW *, int, int, int, char *, chtype);
#endif /* RECMANIP_H */
In one of my files, I call this function like this:
/* recmanip.c */
#include "recmanip.h"
int add_record(void)
{
FIELD *field[NFIELDS];
FORM *myform;
WINDOW *form_win;
int ch, i=0, j=0;
struct form form_data[] = {
{"id", "" }, {"title", "" }, {"artist", "" }, {"hd", "" },
{"bank", "" }, {"bookmark", "" }, {"active", "" }, {"digitalinput",
"" },
{"genre", "" }, {"price", "" }, {"year", "" }, {"remixer", "" },
{"labelid", "" }, {"class", "" }, {"classnumber", "" }
};
===> populate_edit_form(field, myform, form_win);

I'm getting a blank form. I could put all of this in one block, but,
when I want to delete a record,
I don't want to write duplicate code, hence, passing the FIELD, FORM, & WINDOW
objects. The address for the form
is being passed to the function, but, I'm not sure if I'm declaring it right.
I'm still getting used to pointers
and array-pointers. Thanks.
