Remarks

This method appends a block of data to the specified AppendBlob in the container currently selected by Container. The block of data is immediately available as part of the append blob, which must already exist.

Up to 4MB (4194304 bytes) of data may be appended in a single block, and up to 50000 blocks may be appended to a single append blob.

If the specified blob has an active lease, its lease Id must be specified using LeaseId, or the request will fail.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
