.TH menu_userptr 3X ""
.SH NAME
\fBmenu_userptr\fR - associate application data with a menu item
.SH SYNOPSIS
\fB#include <menu.h>\fR
.br
int set_menu_userptr(MENU *menu, void *userptr);
.br
void *menu_userptr(const MENU *menu);
.br
.SH DESCRIPTION
Every menu and 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 the menu user pointer field.
.SH RETURN VALUE
\fBmenu_userptr\fR returns a pointer (which may be \fBNULL\fR).
It does not set errno.
.PP
\fBset_menu_userptr\fP 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.
