.SH NAME
\fBmenu_mark\fR - get and set the menu mark string
.SH SYNOPSIS
\fB#include <menu.h>\fR
.br
int set_menu_mark(MENU *menu, const char *mark);
.br
const char *menu_mark(const MENU *menu);
.br
.SH DESCRIPTION
In order to make menu selections visible on older terminals without
highlighting or color capability, the menu library marks selected items
in a menu with a prefix string.

The function \fBset_menu_mark\fR sets the mark string for the given menu.
Calling \fBset_menu_mark\fR with a null menu item will abolish the mark string.
Note that changing the length of the mark string for a menu while the
menu is posted is likely to produce unhelpful behavior.

The default string is "-" (a dash). Calling \fBset_menu_mark\fR with
a \fBNULL\fR menu argument will change this default.

The function \fBmenu_mark\fR returns the menu's mark string (or \fBNULL\fR if
there is none).
.SH RETURN VALUE
The function \fBmenu_mark\fR returns \fBNULL\fR on error.  The function
\fBset_menu_mark\fR may return the following error codes:
.TP 5
\fBE_OK\fR
The routine succeeded.
.TP 5
\fBE_SYSTEM_ERROR\fR
System error occurred (see \fBerrno\fR).
.TP 5
\fBE_BAD_ARGUMENT\fR
Routine detected an incorrect or out-of-range argument.
.SH SEE ALSO
\fBcurses\fR(3X), \fBmenu\fR(3X).
.SH NOTES
The header file \fB<menu.h>\fR automatically includes the header file
\fB<curses.h>\fR.
.SH PORTABILITY
These routines emulate the System V menu library.  They were not supported on
Version 7 or BSD versions.
