form_field - make and break connections between fields and forms #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 NULL on error. The function field_count returns ERR (the general curses error return value) on error. The functions set_form_fields and move_field return one of the following codes on error:

5 E_OK The routine succeeded.

5 E_SYSTEM_ERROR System error occurred (see errno).

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

5 E_POSTED The form is already posted.

5 E_CONNECTED The field is already connected to a form.

curses(3X), form(3X). 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). Juergen Pfeifer.
