HexToBin function deprecated

In unit Classes

use procedures from unit StrUtils

Convert a hexadecimal string to a binary buffer.

Declaration

pascal
function HexToBin(HexValue: PAnsiChar; BinValue: PAnsiChar; 
 BinBufSize: Integer): Integer

Description

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.

Errors

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