An override for a file download initiation operation.

Syntax

ANSI (Cross Platform)
virtual int FireDownloadFile(FTPServerDownloadFileEventParams *e);
typedef struct {
int64 ConnectionID;
const char *Path;
int64 RestartAt;
int OperationStatus; int reserved; } FTPServerDownloadFileEventParams; Unicode (Windows) virtual INT FireDownloadFile(FTPServerDownloadFileEventParams *e);
typedef struct {
LONG64 ConnectionID;
LPCWSTR Path;
LONG64 RestartAt;
INT OperationStatus; INT reserved; } FTPServerDownloadFileEventParams;
- (void)onDownloadFile:(long long)connectionID :(NSString*)path :(long long)restartAt :(int*)operationStatus;
#define EID_FTPSERVER_DOWNLOADFILE 26

virtual INT SECUREBLACKBOX_CALL FireDownloadFile(LONG64 &lConnectionID, LPSTR &lpszPath, LONG64 &lRestartAt, INT &iOperationStatus);

Remarks

The class fires this event to let the application perform an overridden file download initiation operation.

This event only fires if Action = fraCustom was passed back from BeforeDownloadFile event, and expects your code to perform the requested operation inside the handler. No default operation will be performed by the server component.

Use the OperationStatus parameter to return the operation result back to the server.

This event will be followed by a number of ReadFile calls, requesting the file data from your code, followed by a single TransferCompleted call.

Set OperationStatus to one of the following values:

ostOk1
ostNoSuchFile2
ostAccessDenied3
ostWriteProtect4
ostUnsupported5
ostInvalidParameter6
ostEOF7
