AT_ERRCODE ACCUAPI IG_errmngr_callback_set( LPVOID lpPrivate, LPFNIG_ERRMNGR_ADD lpfnAddCB, LPFNIG_ERRMNGR_CLEAR lpfnClearCB ); |
Name | Type | Description |
---|---|---|
lpPrivate | LPVOID | Any Private data that will be passed to lpfnAddCB and lpfnClearCB callbacks. NULL is acceptable. |
lpfnAddCB | LPFNIG_ERRMNGR_ADD | Callback function that will be called after the record is added to the error stack. See LPFNIG_ERRMNGR_ADD for a declaration. |
lpfnClearCB | LPFNIG_ERRMNGR_CLEAR | Callback function that will be called after the error stack is cleared. See LPFNIG_ERRMNGR_CLEAR for a declaration. |

Global private data and callback functions can be obtained using IG_errmngr_callback_get function.
Each thread has its own independent error stack. There are two types of callbacks - local to thread and global. This API allows you to get the global (thread independent) callbacks. Use IG_err_callback_set to set the thread specific data and callbacks.
