| <H2>NAME</H2><PRE> |
| <STRONG>mitem_new</STRONG> - create and destroy menu items |
| |
| |
| </PRE> |
| <H2>SYNOPSIS</H2><PRE> |
| <STRONG>#include</STRONG> <STRONG><menu.h></STRONG> |
| ITEM *new_item(const char *name, const char *description); |
| int free_item(ITEM *item); |
| |
| |
| </PRE> |
| <H2>DESCRIPTION</H2><PRE> |
| The function <STRONG>new_item</STRONG> allocates a new item and initializes |
| it from the <STRONG>name</STRONG> and <STRONG>description</STRONG> pointers. Please notice |
| that the item stores only the pointers to the name and |
| description. Those pointers must be valid during the life- |
| time of the item. So you should be very careful with names |
| or descriptions allocated on the stack of some routines. |
| The function <STRONG>free_item</STRONG> de-allocates an item. Please notice |
| that it is the responsibility of the application to |
| release the memory for the name or the description of the |
| item. |
| |
| |
| </PRE> |
| <H2>RETURN VALUE</H2><PRE> |
| The function <STRONG>new_item</STRONG> returns <STRONG>NULL</STRONG> on error. It sets |
| errno according to the function's failure: |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |
| Routine detected an incorrect or out-of-range argu- |
| ment. |
| |
| <STRONG>E_SYSTEM_ERROR</STRONG> |
| System error occurred, e.g., malloc failure. |
| |
| The function <STRONG>free_item</STRONG> returns one of the following: |
| |
| <STRONG>E_OK</STRONG> The routine succeeded. |
| |
| <STRONG>E_BAD_ARGUMENT</STRONG> |
| Routine detected an incorrect or out-of-range argu- |
| ment. |
| |
| <STRONG>E_CONNECTED</STRONG> |
| Item is connected to a menu. |
| |
| <STRONG>E_SYSTEM_ERROR</STRONG> |
| System error occurred (see <STRONG>errno</STRONG>). |
