CRC16C_UpdateStr

void CRC16C_UpdateStr( [ in,out ]CRC16C_Context* pContext, [ in , string ] unsigned char* pSrc );

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 null-terminated string with which to update the context.

Remarks

Updates (based on CRC16C checksum algorithm) the pContext context with the null-terminated string specified by pSrc. Call this function for each null-terminated string for which the checksum is calculated. To retrieve the checksum after using CRC16C_UpdateStr, call CRC16C_Final or CRC16C_FinalHex.

Note. Before the first call to CRC16C_Update, CRC16C_UpdateStr, CRC16C_Final or CRC16C_FinalHex functions, the context must be initialized with CRC16C_Init.

VB Example

Private Sub MyButton_Click()   

    Dim Context As CRC16C_Context

    Dim Checksum As CRC16C_Digest

    Dim MyStrData As String

    MyStrData = "Hello World!"

    'Initialize the context

    CRC16C_Init Context

    'Update the context

    CRC16C_UpdateStr Context, MyStrData

    'Get the checksum

    CRC16C_Final Context, Checksum

    'Show the hexadecimal representation of the checksum

    MsgBox QHASH_ConvertToHex(Checksum.Value(0), CRC16C_DIGESTSIZE, True)

End Sub
