    void set_OnFindFirst(TElSFTPServerFindFirstEvent|callable|NULL $Value)
    callable TElSFTPServerFindFirstEvent(TObject $Sender, string $Path, TSBPointer $Data, TElSftpFileInfo $Info, integer &$ErrorCode, string &$Comment)

            //...
        }
    }

Parameters

Path - path to the directory to be scanned
Data - pass some user object (e.g. file search handle) to it. Every consequent call to OnFindNext event will return this object to you as OnFindNext.Data parameter. If you do not need to store some search-related object, set the value of this parameter to null.
Info - information about element to be found (currently none)
ErrorCode - the error code, see values below
Comment - server comment
pcPath - path to the directory to be scanned
szPath - the length of pcPath.
pcComment - server comment
szComment - the length of pcComment.
