50 The function \fBset_current_field\fP sets the current field of the given
51 form; \fBcurrent_field\fP returns the current field of the given form.
53 The function \fBunfocus_current_field\fP removes the focus from the current
55 In such state, inquiries via \fBcurrent_field\fP shall return a NULL pointer.
57 The function \fBset_form_page\fP sets the form's page number (goes to page
60 The function \fBform_page\fP returns the form's current page number.
62 The function \fBfield_index\fP returns the index of the field in the
63 field array of the form it is connected to.
64 It returns \fBERR\fP if
65 the argument is the null pointer or the field is not connected.
67 Except for \fBform_page\fP, each routine returns one of the following:

73 Routine detected an incorrect or out-of-range argument.
76 Routine was called from an initialization or termination function.
79 Contents of a field are not valid.
82 The form driver could not process the request.
85 System error occurred (see \fBerrno\fP(3)).
87 These routines emulate the System V forms library.
