Comments
pTRANSFEROPTIONS is a pointer to a TRANSFEROPTIONS structure. Where the function parameter type is pTRANSFEROPTIONS, you can declare a TRANSFEROPTIONS variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pTRANSFEROPTIONS variable is necessary only if your program requires a pointer.
TRANSFEROPTIONS is used with the LTwain::SetTransferOptions and LTwain::GetTransferOptions functions.
