◆ Flush() ◆ Write() ERW_Result SNetStorageObjectIState::Write ( const void *  buf, size_t  count, size_t *  bytes_written  ) finalvirtual

Write up to "count" bytes from the buffer pointed to by the "buf" argument onto the output device.

Always store the number of bytes actually written, or 0 if "count" has been passed as 0 ("buf" must be ignored in this case), via the "bytes_written" pointer, if provided non-NULL. Note that the method can return non-eRW_Success in case of an I/O error along with indicating (some) data delivered to the output device (and reflected in "*bytes_written").

Note
Apparently, may not return eRW_Success if hasn't been able to write "count" bytes as requested, and "bytes_written" was passed as NULL.
When returning "*bytes_written" as zero for a non-zero "count" requested, the return status should not indicate eRW_Success.
Warning
"*bytes_written" may never be returned greater than "count".
Attention
It is implementation-dependent whether the call blocks until the entire buffer or only some data has been written out. In general, it is advised that this call is made within a loop that checks for errors and proceeds with the writing until the required amount of data has been sent.

Implements IWriter.
