33 \fBmitem_new\fR \- create and destroy menu items
35 \fB#include <menu.h>\fR
37 ITEM *new_item(const char *name, const char *description);
39 int free_item(ITEM *item);
42 The function \fBnew_item\fR allocates a new item and initializes it from the
43 \fBname\fR and \fBdescription\fR pointers. Please notice that the item stores
44 only the pointers to the name and description. Those pointers must be valid
45 during the lifetime of the item. So you should be very careful with names
46 or descriptions allocated on the stack of some routines.
48 The function \fBfree_item\fR de-allocates an item. Please notice that it
49 is the responsibility of the application to release the memory for the
50 name or the description of the item.
52 The function \fBnew_item\fR returns \fBNULL\fR on error.
53 It sets errno according to the function's failure:
56 Routine detected an incorrect or out-of-range argument.
59 System error occurred, e.g., malloc failure.
61 The function \fBfree_item\fR returns one of the following:
64 The routine succeeded.
67 Routine detected an incorrect or out-of-range argument.
70 Item is connected to a menu.
73 System error occurred (see \fBerrno\fR).
75 \fBcurses\fR(3X), \fBmenu\fR(3X).
77 The header file \fB<menu.h>\fR automatically includes the header file
80 These routines emulate the System V menu library. They were not supported on
81 Version 7 or BSD versions.
