</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
The function <STRONG>set_field_opts</STRONG> sets all the given field's option bits
(field option bits may be logically-OR'ed together).
The function <STRONG>field_opts_on</STRONG> turns on the given option bits, and leaves
others alone.
The function <STRONG>field_opts_off</STRONG> turns off the given option bits, and leaves
others alone.
The function <STRONG>field_opts</STRONG> 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
option 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
remains 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 <STRONG>set_max_field</STRONG> function checks for this extension, which allows
a dynamic field to shrink if the new limit is smaller than the
current field size.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
Except for <STRONG>field_opts</STRONG>, each routine returns one of the following:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argument.
<STRONG>E_CURRENT</STRONG>
The field is the current field.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno(3)</STRONG>).
