Calculates the Cyclical Redundancy Check (CRC) of buffer. Remark: CRC is comparable to a stamp signature. Any modification made to the buffer changes the CRC value. The use of CRC allows you to detect the possible file modifications during a transfer via network. You can compare the CRC of the file before and after transmission. If they are identical, the file was probably not modified during the transfer.
CRC is int
CRC = sComputeCrc32(MyString)
IF sComputeCrc32(MyString) <> CRC THEN Info("Modified string")
Sintaxis
<Result> = sComputeCrc32(<Buffer> [, <Partial CRC>])
<Result>: Integer Control value of string (CRC) <Buffer>: Buffer or character string String or buffer used to calculate the control value (CRC) <Partial CRC>: Optional integer Result of a previous CRC calculation. This parameter is used to calculate the CRC of two consecutive buffers: it is not necessary to concatenate the buffers. This parameter corresponds to 0 (a single buffer is managed) by default. Observaciones sComputeCrc32 is identical to sComputeCrc16, but it is faster and more efficient. Clasificación Lógica de negocio / UI: Lógica de negocio
