Write is used to write a part of the file starting from the current file position. The file position is advanced by the number of bytes written.
Signature
Write(
[in] UInt32 fileHandle
[in] ByteString data
);
|
Argument |
Description |
|
fileHandle |
A handle indicating the access request and thus indirectly the position inside the file. |
|
data |
Contains the data to be written at the position of the file. It is server-dependent whether the written data are persistently stored if the session is ended without calling the Close Method with the fileHandle. Writing an empty or null ByteString returns a Good result code without any affect on the file. |
