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, 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 do not fit on a line are wrapped to the next line.  Words are  blank-sepa-
	    rated.

       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 argument.

       E_CURRENT
	    The field is the current field.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

SEE ALSO
       curses(3X), form(3X).

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 supported on  Version	7
       or BSD versions.
