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