Specifies the name of the file to contain the reply data from the server application. Call this method only if the job's type is BG_JOB_TYPE_UPLOAD_REPLY.
HRESULT SetReplyFileName( LPCWSTR ReplyFileName );
Null-terminated string that contains the full path to the reply file. BITS generates the file name if ReplyFileNamePathSpec is NULL or an empty string. You cannot use wildcards in the path or file name, and directories in the path must exist. The path is limited to MAX_PATH, not including the null terminator. The user must have permissions to write to the directory. BITS does not support NTFS streams. Instead of using network drives, which are session specific, use UNC paths (for example, \server\share\path\file). Do not include the \? prefix in the path.
This method returns the following HRESULT values, as well as others.
||Successfully specified the name of the file to contain the reply data.|
||You cannot change the reply file name after BITS begins transferring the reply to the client. BITS is transferring the reply to the client if the state is BG_JOB_STATE_TRANSFERRING and the BytesTotal member of the BG_JOB_REPLY_PROGRESS structure is not BG_SIZE_UNKNOWN.|
||User does not have permission to write to the specified directory on the client.|
||The reply file name is invalid or exceeds MAX_PATH.|
BITS generates the file name if you do not call the SetReplyFileName method before calling the IBackgroundCopyJob::Resume method for the first time.
If BITS generates the file name, the reply file is written to the same directory as the local upload file.
You can call the SetReplyFileName method anytime before BITS begins downloading the reply from the server application; the method fails if the download has begun.
The reply file is available to the client after calling the IBackgroundCopyJob::Complete method. To retrieve the reply data before calling the Complete method, call the IBackgroundCopyJob2::GetReplyData method.
The file is empty if the server application did not provide a reply.
