roar_str2codec(3) System Manager's Manual: RoarAudio roar_str2codec(3)NAME
roar_str2codec - Get codec ID by codec name
roar_codec2str - Get codec name by ID
SYNOPSIS
#include <roaraudio.h>
int roar_str2codec (char * codec);
char * roar_codec2str (int codec);
DESCRIPTION
roar_str2codec converts a string to a RoarAudio Codec ID. It also supports some common aliases. roar_codec2str is the reverse operation of
roar_str2codec: It get's a name by the ID given. If a codec is valid the following should be true:
roar_str2codec(roar_codec2str(codec)) == codec
Note that because of aliasing and case insensitivity the revers operation needs not to be true.
THREAD SAFETY
Because roar_codec2str returns a static unique pointer for each codec it is fully thread safe.
RETURN VALUE
On success roar_str2codec returns a codec ID. On error, -1 is returned. roar_codec2str returns the name of the codec or NULL on error.
You must not free this pointer or write to it.

roar_simple_play(3) System Manager's Manual: RoarAudio roar_simple_play(3)NAME
roar_simple_play, roar_simple_monitor, roar_simple_record, roar_simple_filter - Simple playback, monetoring, recording or filtering via
RoarAudio
SYNOPSIS
#include <roaraudio.h>
int roar_simple_play(int rate, int channels, int bits, int codec, char * server, char * name);
int roar_simple_monitor(int rate, int channels, int bits, int codec, char * server, char * name);
int roar_simple_record(int rate, int channels, int bits, int codec, char * server, char * name);
int roar_simple_filter(int rate, int channels, int bits, int codec, char * server, char * name);
DESCRIPTION
Open a connection to the roard(1) and creates a new stream for playback, monetoring, recording or filtering. After you are done you need
to close the connection via roar_simple_close(3). In case you just don't do anything with the stream the server will kick your connection,
or, in case of playback warns the user about underruns.
All those functions are marked obsolete and will be removed soon. Please upgrade to VS API. See roar_vs_new_simple(3).
PARAMETERS
rate The sample rate of the stream.
channels
The nummber of channels in the stream.
bits The number of bits per sample of the stream. Commen values are 8 and 16.
codec The Codec of the data you stream to the server. This has nothing to do with codec of the file you are playing back or encoding.
Default (ROAR_CODEC_DEFAULT) is ROAR_CODEC_PCM_S_BE for signed PCM in big endian.
server The name of the server. A value of NULL (common case) is used to try default locations.
name The name of the process opening this stream to be listend in the servers meta data. Should normaly be the name of the player with-
out any path or filename being played. If NULL an internal default is used.
NOTES ON FILTER STREAMS
Filtering streams should not expected to work with diffrent audio data than the server works with. You should get the values via
roar_server_oinfo(3) before opening the stream.
RETURN VALUE
On success these calls return a filehandle for the stream. On error, -1 is returned.
EXAMPLES
Examples of these calls are the tools roarcat(1), roarmon(1), roarrec(1) and roarfilt(1). Just look at there code. They aren't that com-
plex.
