Comments

pAPPLICATIONDATA is a pointer to a APPLICATIONDATA structure. Where the function parameter type is pAPPLICATIONDATA, you can declare an APPLICATIONDATA variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pAPPLICATIONDATA variable is necessary only if your program requires a pointer.

APPLICATIONDATA is used with the LTwain::InitSession function.
