NAME
       form_field_opts - set and get field options

SYNOPSIS
       #include <form.h>
       int set_field_opts(FIELD *field, Field_Options opts);
       int field_opts_on(FIELD *field, Field_Options opts);
       int field_opts_off(FIELD *field, Field_Options opts);
       Field_Options field_opts(const FIELD *field);

DESCRIPTION
       The  function  set_field_opts  sets all the given field's option bits (field option bits may be logi-cally-OR'ed logically-OR'ed
       cally-OR'ed together).

       The function field_opts_on turns on the given option bits, and leaves others alone.

       The function field_opts_off turns off the given option bits, and leaves others alone.

       The function field_opts returns the field's current option bits.

       The following options are defined (all are on by default):

       O_VISIBLE
            The field is displayed.  If this option is off, display of the field is suppressed.

       O_ACTIVE
            The field is visited during processing.  If this option is off, the field will not be  reachable
            by navigation keys. Please notice that an invisible field appears to be inactive also.

       O_PUBLIC
            The field contents are displayed as data is entered.

       O_AUTOSKIP

       O_NULLOK
            Allow a blank field.

       O_STATIC
            Field  buffers  are  fixed  to  field's original size.  Turn this option off to create a dynamic
            field.

       O_PASSOK
            Validate field only if modified by user.
