32.SH NAME
Steve Kondikae271bc2015-11-15 02:50:53 +010033\fBmitem_new\fR \- create and destroy menu items
Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +053034.SH SYNOPSIS
35\fB#include <menu.h>\fR
36.br
37ITEM *new_item(const char *name, const char *description);
38.br
39int free_item(ITEM *item);
40.br
41.SH DESCRIPTION
42The 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
44only the pointers to the name and description. Those pointers must be valid
45during the lifetime of the item. So you should be very careful with names
46or descriptions allocated on the stack of some routines.
47.br
48The function \fBfree_item\fR de-allocates an item. Please notice that it
49is the responsibility of the application to release the memory for the
50name or the description of the item.
51.SH RETURN VALUE
52The function \fBnew_item\fR returns \fBNULL\fR on error.
53It sets errno according to the function's failure:
54.TP 5
55.B E_BAD_ARGUMENT
56Routine detected an incorrect or out-of-range argument.
57.TP 5
58.B E_SYSTEM_ERROR
59System error occurred, e.g., malloc failure.
60.PP
61The function \fBfree_item\fR returns one of the following:
62.TP 5
63.B E_OK
64The routine succeeded.
65.TP 5
66.B E_BAD_ARGUMENT
67Routine detected an incorrect or out-of-range argument.
68.TP 5
69.B E_CONNECTED
70Item is connected to a menu.
71.TP 5
72.B E_SYSTEM_ERROR
73System error occurred (see \fBerrno\fR).
74.SH SEE ALSO
75\fBcurses\fR(3X), \fBmenu\fR(3X).
76.SH NOTES
77The header file \fB<menu.h>\fR automatically includes the header file
78\fB<curses.h>\fR.
79.SH PORTABILITY
80These routines emulate the System V menu library. They were not supported on
81Version 7 or BSD versions.
