ReadFile Event
Requests a piece of file data from the application.
Syntax
ANSI (Cross Platform) virtual int FireReadFile(FTPServerReadFileEventParams *e);
typedef struct {
int64 ConnectionID;
int Size;
int OperationStatus; int reserved; } FTPServerReadFileEventParams; Unicode (Windows) virtual INT FireReadFile(FTPServerReadFileEventParams *e);
typedef struct {
LONG64 ConnectionID;
INT Size;
INT OperationStatus; INT reserved; } FTPServerReadFileEventParams;
- (void)onReadFile:(long long)connectionID :(int)size :(int*)operationStatus;
#define EID_FTPSERVER_READFILE 33 virtual INT SECUREBLACKBOX_CALL FireReadFile(LONG64 &lConnectionID, INT &iSize, INT &iOperationStatus);
Remarks
The class fires this event repeatedly during an overridden download operation to request file data from the application.
The handler of this event should read up to Size bytes from the downloaded file, and pass them to the component with a SetClientBuffer call.
Use the OperationStatus parameter to return the operation result back to the server. When the file has been read up to its end, set OperationStatus to ostEOF to tell the components that no more ReadFile calls are needed.
Set OperationStatus to one of the following values:
ostOk | 1 | |
ostNoSuchFile | 2 | |
ostAccessDenied | 3 | |
ostWriteProtect | 4 | |
ostUnsupported | 5 | |
ostInvalidParameter | 6 | |
ostEOF | 7 |
