<H2>NAME</H2><PRE>
<STRONG>form</STRONG> - curses extension for programming forms
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><form.h></STRONG>
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <STRONG>form</STRONG> library provides terminal-independent facilities
for composing form screens on character-cell terminals.
The library includes: field routines, which create and
modify form fields; and form routines, which group fields
into forms, display forms on the screen, and handle inter-
action with the user.
The <STRONG>form</STRONG> library uses the <STRONG>curses</STRONG> libraries, and a curses
initialization routine such as <STRONG>initscr</STRONG> must be called
before using any of these functions. To use the <STRONG>form</STRONG>
library, link with the options <STRONG>-lform</STRONG> <STRONG>-lcurses</STRONG>.
<STRONG>Current</STRONG> <STRONG>Default</STRONG> <STRONG>Values</STRONG> <STRONG>for</STRONG> <STRONG>Field</STRONG> <STRONG>Attributes</STRONG>
The <STRONG>form</STRONG> library maintains a default value for field
attributes. You can get or set this default by calling
the appropriate <STRONG>set_</STRONG> or retrieval routine with a <STRONG>NULL</STRONG>
field pointer. Changing this default with a <STRONG>set_</STRONG> function
affects future field creations, but does not change the
rendering of fields already created.
<STRONG>Routine</STRONG> <STRONG>Name</STRONG> <STRONG>Index</STRONG>
The following table lists each <STRONG>form</STRONG> routine and the name
of the manual page on which it is described.

<H2>RETURN VALUE</H2><PRE>
Routines that return pointers return <STRONG>NULL</STRONG> on error. Rou-
tines that return an integer return one of the following
error codes:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_CONNECTED</STRONG>
The field is already connected to a form.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno</STRONG>).
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argu-
ment.
<STRONG>E_POSTED</STRONG>
The form is already posted.
<STRONG>E_BAD_STATE</STRONG>
Routine was called from an initialization or termina-
tion function.
<STRONG>E_NO_ROOM</STRONG>
Form is too large for its window.
<STRONG>E_NOT_POSTED</STRONG>
The form has not been posted.
<STRONG>E_UNKNOWN_COMMAND</STRONG>
The form driver code saw an unknown request code.
<STRONG>E_INVALID_FIELD</STRONG>
Contents of a field are not valid.
<STRONG>E_NOT_CONNECTED</STRONG>
No fields are connected to the form.
<STRONG>E_REQUEST_DENIED</STRONG>
The form driver could not process the request.
</PRE>
<H2>SEE ALSO</H2><PRE>
<STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> and related pages whose names begin "form_" for
detailed descriptions of the entry points.
</PRE>
<H2>NOTES</H2><PRE>
The header file <STRONG><form.h></STRONG> automatically includes the header
files <STRONG><curses.h></STRONG> and <STRONG><eti.h></STRONG>.
In your library list, libform.a should be before libn-
curses.a; that is, you want to say `-lform -lncurses', not
the other way around (which would give you a link error
using GNU <STRONG><A HREF="ld.1.html">ld(1)</A></STRONG> and many other linkers).
</PRE>
<H2>PORTABILITY</H2><PRE>
These routines emulate the System V forms library. They
were not supported on Version 7 or BSD versions.
