+ <STRONG>#include</STRONG> <STRONG><form.h></STRONG>
+ 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 <STRONG>new_field</STRONG> 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 <STRONG>dup_field</STRONG> 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 <STRONG>link_field</STRONG> acts like <STRONG>dup_field</STRONG>, but the new
+ field shares buffers with its parent. Attribute data is
+ separate.
+
+ The function <STRONG>free_field</STRONG> de-allocates storage associated
+ with a field.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ The function, <STRONG>new_field</STRONG>, <STRONG>dup_field</STRONG>, <STRONG>link_field</STRONG> return <STRONG>NULL</STRONG>
+ on error.
+
+ The function <STRONG>free_field</STRONG> returns one of the following:
+
+ <STRONG>E_OK</STRONG> The routine succeeded.
+
+ <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.

+<H2>NOTES</H2><PRE>
+ The header file <STRONG><form.h></STRONG> automatically includes the header
+ file <STRONG><curses.h></STRONG>.
+ 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 <STRONG><A HREF="dup_field.3x.html">dup_field(3X)</A></STRONG> being portable; the System V forms
+ library documents are not very explicit on what gets
+ copied and was not.
