| <H2>NAME</H2><PRE> |
| <STRONG>menu_userptr</STRONG> - associate application data with a menu item |
| |
| |
| </PRE> |
| <H2>SYNOPSIS</H2><PRE> |
| <STRONG>#include</STRONG> <STRONG><menu.h></STRONG> |
| int set_menu_userptr(MENU *menu, void *userptr); |
| void *menu_userptr(const MENU *menu); |
| |
| |
| </PRE> |
| <H2>DESCRIPTION</H2><PRE> |
| Every menu and 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 |
| the menu user pointer field. |
| |
| |
| </PRE> |
| <H2>RETURN VALUE</H2><PRE> |
| <STRONG>menu_userptr</STRONG> returns a pointer (which may be <STRONG>NULL</STRONG>). It |
| does not set errno. |
| |
| <STRONG>set_menu_userptr</STRONG> returns <STRONG>E_OK</STRONG> (success). |

| <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. |
