       FIELD *new_field(int height, int width,
                        int toprow, int leftcol,
                        int offscreen, int nbuffers);

<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></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><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       The function, <STRONG>new_field</STRONG>, <STRONG>dup_field</STRONG>, <STRONG>link_field</STRONG> return <STRONG>NULL</STRONG>
       on error.  They set errno according to their success:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine  detected  an incorrect or out-of-range argu-
            ment.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred, e.g., malloc failure.

       The function <STRONG>free_field</STRONG> 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  argu-
            ment.

       <STRONG>E_CONNECTED</STRONG>
            field is connected.

       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>dup_field</STRONG> being portable; the System  V  forms  library
       documents are not very explicit about what gets copied and
       what does not.
