The array must be terminated by a \fBNULL\fR. .PP The function \fBform_fields\fR returns the field array of the given form. .PP The function \fBfield_count\fR returns the count of fields in \fIform\fR. .PP The function \fBmove_field\fR moves the given field (which must be disconnected) to a specified location on the screen. .SH RETURN VALUES The function \fBform_fields\fR returns a pointer (which may be \fBNULL\fR). It does not set errno. .PP The function \fBfield_count\fR returns \fBERR\fR if the \fIform\fP parameter is \fBNULL\fP. .PP The functions \fBset_form_fields\fR and \fBmove_field\fR return one of the following codes on error: .TP 5 .B E_OK The routine succeeded. .TP 5 .B E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. .TP 5 .B E_CONNECTED The field is already connected to a form. .TP 5 .B E_POSTED The form is already posted. .TP 5 .B E_SYSTEM_ERROR System error occurred (see \fBerrno\fR). .SH SEE ALSO \fBcurses\fR(3), \fBform\fR(3). .SH NOTES The header file \fB<form.h>\fR automatically includes the header file \fB<curses.h>\fR. .SH PORTABILITY These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions. .PP The SVr4 forms library documentation specifies the \fBfield_count\fR error value as -1 (which is the value of \fBERR\fR). .SH AUTHORS Juergen Pfeifer.
