       <STRONG>form_userptr</STRONG> - associate application data with a form item

<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       Every  form  and  every  form item has a field that can be
       used to hold application-specific data (that is, the form-
       driver code leaves it alone).  These functions get and set
       the form user pointer field.


</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       The function <STRONG>form_userptr</STRONG> returns a pointer (which may  be
       <STRONG>NULL</STRONG>).  It does not set errno.

       The function <STRONG>set_form_userptr</STRONG> returns <STRONG>E_OK</STRONG> (success).

       These routines emulate the System V forms  library.   They
       were not supported on Version 7 or BSD versions.

       The user pointer is a void pointer.  We chose not to leave
       it as a char pointer for SVr4 compatibility.
