NAME
set_form_userptr,
form_userptr -
associate application data with a form item
SYNOPSIS
#include <form.h>
int set_form_userptr(FORM *form, void *userptr);
void* form_userptr(const FORM *form);
DESCRIPTION
Every form and every form item has a field that can be used to hold
applicatio-specific data (that is, the for-driver code leaves it alone).
These functions get and set the form user pointer field.
RETURN VALUE
The function form_userptr returns a pointer (which may be
NULL).
It does not set errno.
The function set_form_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.
