Procedure WRITE writes data to a file.

Parameters:

fileHandle - The file handle for the file to which data is to be written. This must identify a file system object of type, NF3REG.

offset - The position within the file at which the write is to begin. An offset of 0 means to write data starting at the beginning of the file.

payload - The data to be written to the file.

syncType - One of the values below.

• UNSTABLE = 0 - Best effort, no promises.
• DATA_SYNC = 1 - Commit all data to stable storage, plus enough metadata for retrieval, before returning.
• FILE_SYNC = 2 - Commit all data and metadata to stable storage before returning.

credential - The credential used for RPC authentication.

Throws:

java.io.FileNotFoundException
