36 \fBitem_count\fP \- make and break connections between items and menus
38 \fB#include <menu.h>\fR
40 \fBint set_menu_items(MENU *\fP\fImenu\fP\fB, ITEM **\fP\fIitems\fP\fB);\fP
42 \fBITEM **menu_items(const MENU *\fP\fImenu\fP\fB);\fP
44 \fBint item_count(const MENU *\fP\fImenu\fP\fB);\fP
47 The function \fBset_menu_items\fR changes the item pointer array of the given
48 \fImenu\fR. The array must be terminated by a \fBNULL\fR.
50 The function \fBmenu_items\fR returns the item array of the given menu.
52 The function \fBitem_count\fR returns the count of items in \fImenu\fR.
54 The function \fBmenu_items\fR returns a pointer (which may be \fBNULL\fR).
55 It does not set \fBerrno\fP.
57 The function \fBitem_count\fR returns \fBERR\fR (the general \fBcurses\fR error
58 return value) if its \fImenu\fP parameter is \fBNULL\fP.
60 The function \fBset_menu_items\fR returns one of the following codes on error:
63 The routine succeeded.
66 Routine detected an incorrect or out-of-range argument.
69 No items are connected to the menu.
72 The menu is already posted.
75 System error occurred (see \fBerrno\fR(3)).
78 \fBcurses\fR(3X), \fBmenu\fR(3X).
80 The header file \fB<menu.h>\fR automatically includes the header file
83 These routines emulate the System V menu library.
84 They were not supported on
85 Version 7 or BSD versions.
87 The SVr4 menu library documentation specifies the \fBitem_count\fR error value
88 as \-1 (which is the value of \fBERR\fR).
