- accessCondition
- AccessCondition
An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.
- options
- BlobRequestOptions
A BlobRequestOptions object that specifies additional options for the request. If null, default options are applied to the request.
- operationContext
- OperationContext
An OperationContext object that represents the context for the current operation.
- Attributes
Remarks
Use this method only in single-writer scenarios. Internally, this method uses the append-offset conditional header to avoid duplicate blocks, which may cause problems in multiple-writer scenarios. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario.
