NAME
       form_field_opts - set and get field options

SYNOPSIS
       #include <form.h>
       int set_field_opts(FIELD *field, OPTIONS opts);
       int field_opts_on(FIELD *field, OPTIONS opts);
       int field_opts_off(FIELD *field, OPTIONS opts);
       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 logically-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_EDIT
            The field can be edited.

       O_WRAP
            Words  that  don't  fit  on  a  line are wrapped to the next line.
            Words are blank-separated.

       O_BLANK
            The field is cleared whenever a character is entered at the  first
            position.

       O_AUTOSKIP
            Skip to the next field when this one fills

       O_NULLOK
            Allow a blank field.

       O_STATIC
            Field buffers are fixed to field's original size.

       O_PASSOK
            Validate field only if modified by user.

RETURN VALUE
       Except for field_opts, each routine returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

       E_CURRENT
            The field is the current field.
