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, dis-
            play 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.

       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
            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.
