field_count, form_fields, move_field, set_form_fields -- form library
Curses Form Library (libform, -lform)
#include <form.h> int field_count(FORM *form); FIELD ** form_fields(FORM *form); int move_field(FIELD *field, int frow, int fcol); int set_form_fields(FORM *form, FIELD **fields);
The field_count() function returns the number of fields that are attached to the given form, if the form argument passed is NULL then field_count() will return -1. The function form_fields() will return a pointer to array of attach fields for the given form, this array is not NULL termi- nated, fields may be attached to the given form by calling set_form_fields(). The fields argument in this function is a pointer to a NULL terminated array of fields that will be attached to the form. If there are already fields attached to the form then they will be detached before the new fields are attached. The new fields given must not be attached to any other form. The move_field() function will move the given field to the location specified by frow and fcol.
Functions returning pointers will return NULL if an error is detected. The functions that return an int will return one of the following error values: E_OK The function was successful. E_CONNECTED The field is connected to a form. E_POSTED The form is currently posted to the screen. E_BAD_ARGUMENT The function was passed a bad argument.
