33 \fBset_item_userptr\fP,
34 \fBitem_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 The function \fBitem_userptr\fR returns a pointer (possibly \fBNULL\fR).
48 It does not set errno.
50 The \fBset_item_userptr\fP always returns \fBE_OK\fP (success).
53 \fBcurses\fR(3X), \fBmenu\fR(3X).
55 The header file \fB<menu.h>\fR automatically includes the header file
58 These routines emulate the System V menu library. They were not supported on
59 Version 7 or BSD versions.
61 The user pointer is a void pointer.
62 We chose not to leave it as a char pointer for SVr4 compatibility.
