31 .TH menu_userptr 3X 2023-10-07 "ncurses 6.4" "Library calls"
33 \fBset_menu_userptr\fP,
35 associate application data with a menu item
40 \fBint set_menu_userptr(MENU *\fImenu\fP, void *\fIuserptr\fP);
41 \fBvoid *menu_userptr(const MENU *\fImenu\fP);
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 The header file \fB<menu.h>\fP automatically includes the header file
56 These routines emulate the System V menu library.
57 They were not supported on
58 Version 7 or BSD versions.
60 The user pointer is a void pointer.
61 We chose not to leave it as a char pointer for SVr4 compatibility.
