write()

bool SkFILEWStream::write ( const void *  buffer, size_t  size  )

overridevirtual

Called to write bytes to a SkWStream. Returns true on success

buffer	the address of at least size bytes to be written to the stream
size	The number of bytes in buffer to write to the stream

Returns

true on success

Implements SkWStream.
