</PRE>
<H2>NAME</H2><PRE>
<STRONG>mitem_userptr</STRONG> - associate application data with a menu
item
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><menu.h></STRONG>
int set_item_userptr(ITEM *item, void *userptr);
void *item_userptr(const ITEM *item);
</PRE>
<H2>DESCRIPTION</H2><PRE>
Every menu item has a field that can be used to hold
application-specific data (that is, the menu-driver code
leaves it alone). These functions get and set that field.
</PRE>
<H2>RETURN VALUE</H2><PRE>
The function <STRONG>item_userptr</STRONG> returns a pointer (possibly
<STRONG>NULL</STRONG>). It does not set errno.
The <STRONG>set_item_userptr</STRONG> always returns <STRONG>E_OK</STRONG> (success).
</PRE>
<H2>SEE ALSO</H2><PRE>
<STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="menu.3x.html">menu(3x)</A></STRONG>.
</PRE>
<H2>NOTES</H2><PRE>
The header file <STRONG><menu.h></STRONG> automatically includes the header
file <STRONG><curses.h></STRONG>.
</PRE>
<H2>PORTABILITY</H2><PRE>
These routines emulate the System V menu library. They
were not supported on Version 7 or BSD versions.
The user pointer is a void pointer. We chose not to leave
it as a char pointer for SVr4 compatibility.
