# form_field_opts 3x

## 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, 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 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.
