47 <STRONG>menu_mark</STRONG> - get and set the menu mark string

53 int set_menu_mark(MENU *menu, const char *mark);
54 const char *menu_mark(const MENU *menu);
58 <H2>DESCRIPTION</H2><PRE>
59 In order to make menu selections visible on older termi-
60 nals without highlighting or color capability, the menu
61 library marks selected items in a menu with a prefix
64 The function <STRONG>set_menu_mark</STRONG> sets the mark string for the
65 given menu. Calling <STRONG>set_menu_mark</STRONG> with a null menu item
66 will abolish the mark string. Note that changing the
67 length of the mark string for a menu while the menu is
68 posted is likely to produce unhelpful behavior.
70 The default string is "-" (a dash). Calling <STRONG>set_menu_mark</STRONG>
71 with a <STRONG>NULL</STRONG> menu argument will change this default.
73 The function <STRONG>menu_mark</STRONG> returns the menu's mark string (or
74 <STRONG>NULL</STRONG> if there is none).
78 <H2>RETURN VALUE</H2><PRE>
79 The function <STRONG>menu_mark</STRONG> returns <STRONG>NULL</STRONG> on error. The func-
80 tion <STRONG>set_menu_mark</STRONG> may return the following error codes:
82 <STRONG>E_OK</STRONG> The routine succeeded.
84 <STRONG>E_SYSTEM_ERROR</STRONG>
85 System error occurred (see <STRONG>errno</STRONG>).
