ssize_t muroar_write (muroar_t fh, const void * buf, size_t len);
DESCRIPTION
This function writes a block of data to a connected stream. It exists to have a portable way to send the data to the sound server that
does not depend on the underlying operating system.
PARAMETERS
fh The stream file handle connected to the server. This must be opend using muroar_stream(3).
buf A pointer to the block of data that should be written.
len The total length in byte of the data that should be written.
RETURN VALUE
On success this call return the number of successful written bytes. On error, -1 is returned.

wait at least some milisecunds.
