.TH mitem_userptr 3X ""
.SH NAME
\fBmitem_userptr\fR \- associate application data with a menu item
.SH SYNOPSIS
\fB#include <menu.h>\fR
.br
int set_item_userptr(ITEM *item, void *userptr);
.br
void *item_userptr(const ITEM *item);
.br
.SH DESCRIPTION
Every menu item has a field that can be used to hold application-specific data
(that is, the menu-driver code leaves it alone).  These functions get and set
that field.
.SH RETURN VALUE
The function \fBitem_userptr\fR returns a pointer (possibly \fBNULL\fR).
It does not set errno.
.PP
The \fBset_item_userptr\fP always returns \fBE_OK\fP (success).
.
.SH SEE ALSO
\fBcurses\fR(3X), \fBmenu\fR(3X).
.SH NOTES
The header file \fB<menu.h>\fR automatically includes the header file
\fB<curses.h>\fR.
.SH PORTABILITY
These routines emulate the System V menu library.  They were not supported on
Version 7 or BSD versions.
.PP
The user pointer is a void pointer.
We chose not to leave it as a char pointer for SVr4 compatibility.
