The array must be terminated by a \fBNULL\fR.The function \fBform_fields\fR returns the field array of the given form.The function \fBfield_count\fR returns the count of fields in \fIform\fR.The function \fBmove_field\fR moves the given field (which must be disconnected)to a specified location on the screen..SH RETURN VALUESThe function \fBform_fields\fR returns \fBNULL\fR on error.The function \fBfield_count\fR returns \fBERR\fR (the general\fBcurses\fR error return value) on error.The functions \fBset_form_fields\fR and \fBmove_field\fR return one ofthe following codes on error:.TP 5\fBE_OK\fRThe routine succeeded..TP 5\fBE_SYSTEM_ERROR\fRSystem error occurred (see \fBerrno\fR)..TP 5\fBE_BAD_ARGUMENT\fRRoutine detected an incorrect or out-of-range argument..TP 5\fBE_POSTED\fRThe form is already posted..TP 5\fBE_CONNECTED\fRThe field is already connected to a form..SH SEE ALSO\fBcurses\fR(3X), \fBform\fR(3X)..SH NOTESThe header file \fB<form.h>\fR automatically includes the header file\fB<curses.h>\fR..SH PORTABILITYThese routines emulate the System V forms library.  They were not supported onVersion 7 or BSD versions.The SVr4 forms library documentation specifies the \fBfield_count\fR error valueas -1 (which is the value of \fBERR\fR)..SH AUTHORSJuergen Pfeifer.
