L_TCHAR * pString

A string containing the built-in tag text, the user can update this value to display instead.

L_VOID *pUserData

A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_DispContainerSetBuiltInTagCallBack.) Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

Value Meaning
SUCCESS The function was successful.
1 An error occurred. Refer to Return Codes.
