NAME
     set_field_userptr,	 field_userptr	- associate application data with a form
     field

SYNOPSIS
     #include <form.h>

     int set_field_userptr(FIELD *field, void *userptr);
     void *field_userptr(const FIELD *field);

DESCRIPTION
     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.

RETURN VALUE
     The function field_userptr returns a pointer (which may be NULL).	It  does
     not set errno.

     The function set_field_userptr returns E_OK (success).

PORTABILITY
     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.
