Имя (Name)
set_form_userptr, form_userptr - associate application data with
a form item
Синопсис (Synopsis)
#include <form.h>
int set_form_userptr(FORM *form, void *userptr);
void* form_userptr(const FORM *form);
Описание (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.
Возвращаемое значение (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).

Примечание (Note)
The header file <form.h> automatically includes the header file
<curses.h>.
Портативность (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.
