muroar_write(3) muRoar Programmer's Manual: IO Extension muroar_write(3)NAME
muroar_write - Write data to a stream in a portable way
SYNOPSIS
#include <muroar.h>
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.
NOTES
This function calls the underlying write function in a loop. If this returns less than the given length you should not re-try directly but
wait at least some milisecunds.
HISTORY
This function first appeared in muRoar version 0.1beta0.

muroar_stream - Create a stream connected to a RoarAudio sound server
SYNOPSIS
#include <muroar.h>
muroar_t muroar_stream (muroar_t fh, int dir, int * stream, int codec, int rate, int channels, int bits);
DESCRIPTION
This function connects a stream to a sound server supporting the RoarAudio protocol. It takes a connected control connection created with
roar_connect(3) and converts it into a connected stream. The socket can no longer be used as control connection.
PARAMETERS
fh The connected control connection.
dir The stream direction for the new stream. For playback of a waveform stream (PCM data) this is MUROAR_PLAY_WAVE. For all possible
values see the offical muRoar manual.
stream This is a pointer to an integer muRoar stores the stream ID in. If your application does not need to know the stream ID of the new
stream this can be set to NULL.
codec This is the codec to be used for the new stream. For signed PCM in host byte order use MUROAR_CODEC_PCM or MUROAR_CODEC_PCM_S. For
unsigned PCM use MUROAR_CODEC_PCM_U. There are a lot other codecs defined. However using a codec not supported by the server will
result an failure of this call. For all possible values see the offical muRoar manual.
rate This is the sample/frame rate the new stream will use. For streams this setting does not make any sense set this to zero.
channels
This is the number of channels for the new stream. For streams this setting does not make any sense set this to zero.
bits This is the number of bits per sample to be used by the data. For streams this setting does not make any sense set this to zero.
RETURN VALUE
On success this call return the new stream IO handle. This may be the same as the control connection or a new one and the control connec-
tion is closed. On error, MUROAR_HANDLE_INVALID is returned.
BUGS
In failure where is no way to tell was was going wrong.
HISTORY
This function first appeared in muRoar version 0.1beta0.
