FORMS(3)                NetBSD Library Functions Manual               FORMS(3)


NAME

     field_count, form_fields, move_field, set_form_fields -- form library


LIBRARY

     Curses Form Library (libform, -lform)


SYNOPSIS

     #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);


DESCRIPTION

     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.


RETURN VALUES

     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.
