34 \fBmitem_userptr\fR - associate application data with a menu item
36 \fB#include <menu.h>\fR
38 int set_item_userptr(ITEM *item, void *userptr);
40 void *item_userptr(const ITEM *item);
43 Every menu item has a field that can be used to hold application-specific data
44 (that is, the menu-driver code leaves it alone). These functions get and set
47 Except for \fBitem_userptr\fR (which returns \fBNULL\fR on error), each function returns one of the following:
50 The routine succeeded.
53 System error occurred (see \fBerrno\fR).
55 \fBcurses\fR(3X), \fBmenu\fR(3X).
57 The header file \fB<menu.h>\fR automatically includes the header file
60 These routines emulate the System V menu library. They were not supported on
61 Version 7 or BSD versions.
