</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
Every form field 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 that field.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
The function <STRONG>field_userptr</STRONG> returns a pointer (which may be
<STRONG>NULL</STRONG>). It does not set errno.
The function <STRONG>set_field_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.
