putRange (method)

Uploads a range of data to a file.

Syntax

- (void)putRange:(NSString*)filePath :(long long)writeOffset;
public func putRange(_ filePath: String, _ writeOffset: Int64) throws -> Void

Remarks

This method uploads a range of data to the file at the specified FilePath in the share currently selected by Share. The data to upload cannot be larger than 4MB (4194304 bytes), and is written to the file at the given WriteOffset (specified in bytes).

The server tracks ranges of file data in 512-byte chunks, aligned to the absolute beginning of the file. However, neither the WriteOffset nor the length of the data to upload need be a multiple of 512. Any portions of a chunk not written to will be populated with 0s.

Note that, according to the Azure File Storage documentation, this operation requires a write lock on the entire file in order to complete successfully.
