form_field.3x - Man Page
make and break connections between fields and forms
Synopsis
#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);
Description
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.
Return Value
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(3)).
Portability
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).
