NAME

     form_field - 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 VALUES

     The function form_fields returns NULL on error.

     The function field_count returns ERR (the general curses
     error return value) on error.

     The functions set_form_fields and move_field return one of
     the following codes on error:

     E_OK The routine succeeded.

     E_SYSTEM_ERROR
          System error occurred (see errno).

     E_BAD_ARGUMENT
          Routine detected an incorrect or out-of-range argument.

     E_POSTED
          The form is already posted.

     E_CONNECTED
          The field is already connected to a form.

SEE ALSO

     curses(3), form(3).

     The header file <form.h> automatically includes the header

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).
