CRC32_Update

void CRC32_Update( [ in,out ]CRC32_Context* pContext, [ in , size_is( nSrcLength ) ] const void* pSrc, [ in ] int nSrcLength );

Parameters

pContext

    [in/out] A memory buffer that is used as the context.

     Note. All predefined types are specified in the Predefined Types List.

 pSrc

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

 nSrcLength

    [in] Length in bytes of the memory block.

Remarks

Updates (based on CRC32 checksum algorithm) the pContext context with the pSrc memory block. Call this function for each continuous memory block of the data for which the checksum is calculated. To retrieve the checksum after using CRC32_Update, call CRC32_Final or CRC32_FinalHex.

Note. Before the first call to CRC32_Update, CRC32_UpdateStr, CRC32_Final or CRC32_FinalHex functions, the context must be initialized with CRC32_Init.

VB Example

See the example for CRC32_Final.
