<H2>NAME</H2><PRE>
<B>form_field_new</B> - create and destroy form fields
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><form.h></B>
FIELD *new_field(int height, int width,
int toprow, int leftcol,
int offscreen, int nbuffers);
FIELD *dup_field(FIELD *field, int toprow, int leftcol);
FIELD *link_field(FIELD *field, int toprow, int leftcol);
int free_field(FIELD *field);
</PRE>
<H2>DESCRIPTION</H2><PRE>
The function <B>new_field</B> allocates a new field and initial-
izes it from the parameters given: height, width, row of
upper-left corner, column of upper-left corner, number
off-screen rows, and number of additional working buffers.
The function <B>dup_field</B> duplicates a field at a new loca-
tion. Most attributes (including current contents, size,
validation type, buffer count, growth threshold, justifi-
cation, foreground, background, pad character, options,
and user pointer) are copied. Field status and the field
page bit are not copied.
The function <B>link_field</B> acts like <B>dup_field</B>, but the new
field shares buffers with its parent. Attribute data is
separate.
The function <B>free_field</B> de-allocates storage associated
with a field.
</PRE>
<H2>RETURN VALUE</H2><PRE>
The function, <B>new_field</B>, <B>dup_field</B>, <B>link_field</B> return <B>NULL</B>
on error.
The function <B>free_field</B> returns one of the following:
<B>E_OK</B> The routine succeeded.
<B>E_SYSTEM_ERROR</B>
System error occurred (see <B>errno</B>).
<B>E_BAD_ARGUMENT</B>
Routine detected an incorrect or out-of-range argu-
ment.

<B><A HREF="ncurses.3x.html">curses(3x)</A></B>, <B><A HREF="form.3x.html">form(3x)</A></B>.
</PRE>
<H2>NOTES</H2><PRE>
The header file <B><form.h></B> automatically includes the header
file <B><curses.h></B>.
</PRE>
<H2>PORTABILITY</H2><PRE>
These routines emulate the System V forms library. They
were not supported on Version 7 or BSD versions.
It may be unwise to count on the set of attributes copied
by <B><A HREF="dup_field.3x.html">dup_field(3x)</A></B> being portable; the System V forms
library documents are not very explicit on what gets
copied and was not.
