L_VOID * pData

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_PrnRegisterJobCallback 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.


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


This callback function gives a status about the print job as it is being started or ended.
