Convert a hexadecimal string to a binary buffer


Source position: classesh.inc line 2192

function HexToBin(

  HexValue: PChar;

  BinValue: PChar;

  BinBufSize: Integer



HexToBin scans the hexadecimal string representation in HexValue and transforms every 2 character hexadecimal number to a byte and stores it in BinValue. The buffer size is the size of the binary buffer. Scanning will stop if the size of the binary buffer is reached or when an invalid character is encountered. The return value is the number of stored bytes.


No length checking is done, so if an invalid size is specified, an exception may follow.
