Member Function Documentation

virtual status_t Sync (   )  [pure virtual]

Make sure all data in the stream is written to its physical device. Returns B_OK if the data is safely stored away, else an error code. Implemented in BStreamDatum::Stream, BBufferIO, BByteStream, BWriteOnlyStream, BIOSStream, BKernelOStr, BMemoryStore, BValueStorage, BNullStream, BPipe, and BWindowsOutputStream.

ssize_t Write (  const void *  buffer, size_t  size, uint32_t  flags = 0 )  [inline]

Convenience for writing a vector of one buffer.

virtual ssize_t WriteV (  const iovec *  vector, ssize_t  count, uint32_t  flags = 0 )  [pure virtual]

Write the bytes described by "iovec" in to the stream. Returns the number of bytes actually written, or a negative error code. A NULL 'vector' is valid if 'count' is <= 0, in which case count is returned. If 'count' is zero and the B_WRITE_END flag is supplied, the stream is truncated at its current location. Writing to a stream will normally block until all bytes have been written; use B_DO_NOT_BLOCK to allow partial writes.
