FastCRC Type Library Overview
FastCRC Library includes fastcrc.tlb file (FastCRC Type Library) with declarations of all functions. This allows to use the FastCRC Library in different programming languages which have the possibility to reference a Type Library, such as VB 5.0, VB 6.0, VBA, etc. )
CRC16 checksums can be generated in two modes: accumulative and non-accumulative.
The accumulative mode is applied when the data for which the checksum is calculated (data) represents one or more continuous memory block(s) or when the data is created at runtime in many steps (for instance, when reading a file).
Non-accumulative mode can be applied when the data represents one continuous memory block, a null-terminated string, or a file.
To generate the checksum in the accumulative mode, perform the following:
Call the FCRC16_Update function for each continuous memory block of data to perform the calculations.
Call the FCRC16_Final function to obtain the checksum.
To generate the checksum in the non-accumulative mode, perform one of the following:
Call the FCRC16_Calculate function if the data represents a continuous memory block.
Call the FCRC16_CalculateStr function if the data represents a null-terminated string.
Call the FCRC16_CalculateFile function if the data represents a file.
