NAME
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
application-specific data (that is, the form-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).
SEE ALSO
ncurses(3NCURSES), form(3FORM).
NOTES
The header file <form.h> automatically includes the header file
<curses.h>.
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.
