Callback function fired for every page printed using the LEADTOOLS Virtual Printer Driver.
Character string that contains the name of the LEADTOOLS Virtual Printer Driver.
Handle to the block of memory that contains an EMF data file.
The size of the data file in memory pointed to by the hMem parameter.
A void pointer that you can use to access a variable or structure that contains 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 passed to the L_PrnRegisterEMFCallback function in the pData parameter.
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
The contents of each printed page will be received in the EMF data file pointed to by the hMem parameter. When the hMem parameter is no longer needed, free it by calling the GlobalFree function.
