## 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).

           were not supported on Version 7 or BSD versions.
