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  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.  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 do not 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.
            Turn this option off to create a dynamic field.

       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_BAD_ARGUMENT
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       E_CURRENT
            The field is the current field.

       E_SYSTEM_ERROR
            System error occurred (see errno).
