FCRC32_Update

void FCRC32_Update( [ in,out ]long* pCRC, [ in , size_is( nSrcLength ) ] const void* pSrc, [ in ] int nSrcLength );

Parameters

pCRC

    [in/out] The crc variable.

 pSrc

    [in] A continuous memory block with which to update the crc variable.

 nSrcLength

    [in] Length in bytes of the memory block.

Remarks

Updates the crc variable specified by pCRC with the memory block specified by pSrc. Call this function for each continuous memory block of the data for which the checksum is calculated. To retrieve the checksum after using FCRC32_Update, call FCRC32_Final.

Note. Before the first call to FCRC32_Update, FCRC32_UpdateStr or FCRC32_Final functions, the crc variable must be initialized with FCRC32_Init.

VB Example

See the example for FCRC32_Final.
