Hash

Create GNU Gettext hash value for a string

Declaration

Source position: objpas.pp line 80

Description

Hash calculates the hash value of the string S in a manner that is compatible with the GNU gettext hash value for the string. It is the same value that is stored in the Resource string tables, and which can be retrieved with the GetResourceStringHash function call.

Errors

None. In case the calculated hash value should be 0, the returned result will be -1.

        <>GetResourceStringHash(I,J) then
        Writeln ('Hash mismatch at ',I,',',J)
      else
        Writeln ('Hash (',I,',',J,') matches.');
