form_userptr - associate application data with a form item
#include <form.h>
int set_form_userptr(FORM *form, void *userptr);
void* form_userptr(const FORM *form);
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 function form_userptr returns a pointer (which may be
NULL). It does not set errno.
The function set_form_userptr returns E_OK (success).
curses(3x), form(3x).
The header file <form.h> automatically includes the header
file <curses.h>.
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.
