set_form_fields (3form)

#include <form.h>

int set_form_fields(FORM *form, FIELD **fields);

FIELD **form_fields(const FORM *form);

int field_count(const FORM *form);

int move_field(FIELD *field, int frow, int fcol);

The function set_form_fields changes the field pointer array of the given form. The array must be terminated by a NULL.

The function form_fields returns the field array of the given form.

The function field_count returns the count of fields in form.

The function move_field moves the given field (which must be disconnected) to a specified location on the screen.

The function form_fields returns a pointer (which may be NULL). It does not set errno.

The function field_count returns ERR if the form parameter is NULL.

The functions set_form_fields and move_field return one of the following codes on error:

E_OK

The routine succeeded.

E_BAD_ARGUMENT

Routine detected an incorrect or out-of-range argument.

E_CONNECTED

The field is already connected to a form.

E_POSTED

The form is already posted.

E_SYSTEM_ERROR

System error occurred (see errno).

ncurses(3NCURSES), form(3FORM).

The header file <form.h> automatically includes the header file <curses.h>.

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.

The SVr4 forms library documentation specifies the field_count error value as -1 (which is the value of ERR).
