C++

bool __fastcall AppendBlock(const System::UnicodeString AContainerName, const System::UnicodeString ABlobName, System::DynamicArray<System::Byte> AContent, const System::UnicodeString AContentMD5, const System::UnicodeString ALeaseId, const System::UnicodeString AClientRequestID, int AMaxSize, int AAppendPos, const TBlobActionConditional &AActionConditional, Data::Cloud::Cloudapi::TCloudResponseInfo* const AResponseInfo);

Description

Appends an array of bytes to the end of an existing append blob, and returns True on success or False otherwise.

AppendBlock receives the following parameters:

• AContainerName is the name of the blob container where the target append blob is.
• ABlobName is the name of the target append blob.
• AContent is the array of bytes to append to the target append blob.
• AContentMD5 (optional) is an MD5 checksum of AContent which the server can use to ensure that AContent was received correctly.
• ALeaseId is the identifier of a lease that is currently active on the target append blob, or an empty string if there is no active lease on the target append blob.
• AClientRequestID is an optional string that uniquely identifies your client. This value is used for storage analytics.
• AMaxSize (optional) is the maximum length (in bytes) permitted for the target append blob.
• AAppendPos (optional) is a number that indicates the expected byte offset. AppendBlock only succeeds if the position where AContent is appended is equal to this number.
• AActionConditional (optional) is a set of conditional headers to include in the request.
• AResponseInfo is an optional instance of TCloudResponseInfo to store the information of the response. Use a nil value if you do not need the information of the response.
