libMySQL.dll

[René Tegel]

I have some problems with the win32 interface dll libMySQL.dll.
Everything works out fine when only retrieving correct queries. 
However, when executing an incorrect query, everything behaves normal until i 
terminate the application (and thus unload the dll).

With other types of access (mysql console (linux, nt, gui) or PHP i notice no problems 
at all.

System: -libmySQL.dll for mysql 3.23 (date: 17-1-2001);
RedHat7, with the rpm of mysql 3.23 installed;
Windows 2000 pro SP1 workstation;
Programming environment: delphi 5.

My interface routines are based on the interface unit by Bob Silva, and like this:

TYPE
{some more type declarations....}
 PMYSQL=^MYSQL;
 MYSQL= record
        _net: NET;
        host,user,passwd,unix_socket,server_version,host_info,info,db: pchar;
        port,client_flag,server_capabilities,protocol_version,field_count: Cardinal;
        thread_id, affected_rows, insert_id, extra_info:longint;
        status: mysql_status;
        fields: PMYSQL_FIELD;
        field_alloc: MEM_ROOT;
        free_me, reconnect: MY_BOOL;
       end;


function mysql_connect( _mysql: pmysql; const 
host,user,passwd:pchar):pmysql;stdcall;external 'libmysql.dll';

procedure mysql_close( _mysql: pmysql); stdcall;external thelib;



function Mysqlconnect(host, user, pass:String): Boolean;
var f:PMySQL;
begin
  f:=mysql_connect (@my_sql_db,PChar(host),PChar(user),PChar(pass));
  Result:= (@my_sql_db=f);
end;

procedure Mysqldisconnect;
begin
 mysql_close(@my_sql_db);
end;


Any ideas?
