32 .TH menu_userptr 3X 2023-09-16 "ncurses 6.4" "Library calls"
34 \fBset_menu_userptr\fP,
36 associate application data with a menu item
38 \fB#include <menu.h>\fP
40 \fBint set_menu_userptr(MENU *\fImenu\fB, void *\fIuserptr\fB);\fR
42 \fBvoid *menu_userptr(const MENU *\fImenu\fB);\fR
44 Every menu and every menu item has a field that can be used to hold
45 application-specific data (that is, the menu-driver code leaves it alone).
46 These functions get and set the menu user pointer field.
48 \fBmenu_userptr\fP returns a pointer (which may be \fBNULL\fP).
49 It does not set \fBerrno\fP.
51 \fBset_menu_userptr\fP returns \fBE_OK\fP (success).
53 \fBcurses\fP(3X), \fBmenu\fP(3X).
55 The header file \fB<menu.h>\fP automatically includes the header file
58 These routines emulate the System V menu library.
59 They were not supported on
60 Version 7 or BSD versions.
62 The user pointer is a void pointer.
63 We chose not to leave it as a char pointer for SVr4 compatibility.
