form_field_opts(3X)					   form_field_opts(3X)

NAME
       set_field_opts, field_opts_on, field_opts_off, field_opts - set and get
       field options

SYNOPSIS
       #include	<form.h>

       int set_field_opts(FIELD	*field,	Field_Options opts);
       Field_Options field_opts(const FIELD *field);

       int field_opts_on(FIELD *field, Field_Options opts);
       int field_opts_off(FIELD	*field,	Field_Options opts);

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 standard options are defined (all are on by default):

       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_AUTOSKIP
	    Skip to the	next field when	this one fills.

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

       O_EDIT
	    The	field can be edited.

       O_NULLOK
	    Allow a blank field.

       O_PASSOK
	    Validate field only	if modified by user.

       O_PUBLIC
	    The	field contents are displayed as	data is	entered.

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

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

       O_WRAP
	    Words  that	 do  not  fit  on a line are wrapped to	the next line.
	    Words are blank-separated.

       These extension options are defined (extensions are off by default):

       O_DYNAMIC_JUSTIFY
	    Permit dynamic fields to be	justified, like	static fields.

       O_NO_LEFT_STRIP
	    Preserve leading whitespace	in the field buffer, which is normally
	    discarded.

       O_EDGE_INSERT_STAY
	    When inserting into	a field	up to the boundary  position,  option-
	    ally  delay	the scrolling, so that the last	inserted character re-
	    mains visible, but advance the cursor to  reflect  the  insertion.
	    This  allows the form library to display the inserted character in
	    one-character fields as well as allowing the library  to  maintain
	    consistent state.

       O_INPUT_FIELD
	    The	set_max_field function checks for this extension, which	allows
	    a  dynamic	field  to  shrink if the new limit is smaller than the
	    current field size.

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 argument.

       E_CURRENT
	    The	field is the current field.

       E_SYSTEM_ERROR
	    System error occurred (see errno(3)).

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

PORTABILITY
       These  routines emulate the System V forms library.  They were not sup-
       ported on Version 7 or BSD versions.
