AT_ERRCODE ACCUAPI IG_errmngr_callback_get( LPVOID FAR* lplpPrivate, LPFNIG_ERRMNGR_ADD FAR* lplpfnAddCB, LPFNIG_ERRMNGR_CLEAR FAR* lplpfnClearCB ); |
Name | Type | Description |
---|---|---|
lplpPrivate | LPVOID FAR* | Pointer to LPVOID variable to retrieve the private data that is passed to *lplpfnAddCB and *lplpfnClearCB callbacks. NULL is acceptable. |
lplpfnAddCB | LPFNIG_ERRMNGR_ADD FAR* | Pointer to LPFNIG_ERRMNGR_ADD variable to retrieve the callback function that is called after the record is added to the error stack. NULL is acceptable. |
lplpfnClearCB | LPFNIG_ERRMNGR_CLEAR FAR* | Pointer to LPFNIG_ERRMNGR_CLEAR variable to retrieve the callback function that is called after the error stack is cleared. NULL is acceptable. |
Returns the code of the ImageGear error that occurred during this function call. A value of zero means no errors have occurred. Errors that occurred during this function call are not appended onto the error stack.
This function does not process image pixels.

Global private data and callback functions can be set using IG_errmngr_callback_set 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_get to get the thread specific data and callbacks.
