33 \fBset_menu_userptr\fP,
34 \fBmenu_userptr\fR \- associate application data with a menu item
36 \fB#include <menu.h>\fR
38 int set_menu_userptr(MENU *menu, void *userptr);
40 void *menu_userptr(const MENU *menu);
43 Every menu and every menu item has a field that can be used to hold
44 application-specific data (that is, the menu-driver code leaves it alone).
45 These functions get and set the menu user pointer field.
47 \fBmenu_userptr\fR returns a pointer (which may be \fBNULL\fR).
48 It does not set errno.
50 \fBset_menu_userptr\fP returns \fBE_OK\fP (success).
52 \fBcurses\fR(3X), \fBmenu\fR(3X).
54 The header file \fB<menu.h>\fR automatically includes the header file
57 These routines emulate the System V menu library. 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.
