NAME
       ffoorrmmuusseerrppttrr - associate application data with a form item

SYNOPSIS
       ##iinncclluuddee <>
       int setformuserptr(FORM *form, void *userptr);
       void* formuserptr(const FORM *form);

DESCRIPTION
       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.

       The  header  file  <>  automatically  includes  the  header  file
       <>.

PPOORRTTAABBIILLIITTYY
       These  routines emulate the System V forms library.  They were not sup-
       ported on Version 7 or BSD versions.

       The user pointer should be a void pointer.   We  leave  it  as  a  char
       pointer for SVr4 compatibility.
