SND_PCM_NEW_STREAM(9) Sound Devices SND_PCM_NEW_STREAM(9)NAME
snd_pcm_new_stream - create a new PCM stream
SYNOPSIS
int snd_pcm_new_stream(struct snd_pcm * pcm, int stream, int substream_count);
ARGUMENTS
pcm
the pcm instance
stream
the stream direction, SNDRV_PCM_STREAM_XXX
substream_count
the number of substreams
DESCRIPTION
Creates a new stream for the pcm. The corresponding stream on the pcm must have been empty before calling this, i.e. zero must be given to
the argument of snd_pcm_new.
Returns zero if successful, or a negative error code on failure.

Audio::FLAC::Decoder - An object-oriented FLAC decoder
SYNOPSIS
use Audio::FLAC::Decoder;
my $decoder = Audio::FLAC::Decoder->open("song.flac");
my $buffer;
while ((my $len = $decoder->sysread($buffer) > 0) {
# do something with the PCM stream
}
OR
open FLAC, "song.flac" or die $!;
my $decoder = Audio::FLAC::Decoder->open(*FLAC);
OR
# can also be IO::Socket or any other IO::Handle subclass.
my $fh = IO::Handle->new("song.flac");
my $decoder = Audio::FLAC::Decoder->open($fh);
DESCRIPTION
This module provides users with Decoder objects for FLAC files. One can read data in PCM format from the stream, seek by pcm samples, or
time.
CONSTRUCTOR
"open ($filename)"
Opens an FLAC file for decoding. It opens a handle to the file or uses an existing handle and initializes all of the internal FLAC decoding
structures. Note that the object will maintain open file descriptors until the object is collected by the garbage handler. Returns "undef"
on failure.
INSTANCE METHODS
"sysread ($buffer, [$size])"
Reads PCM data from the FLAC stream into $buffer. Returns the number of bytes read, 0 when it reaches the end of the stream, or a value
less than 0 on error. The optional size can specify how many bytes to read.
"raw_seek ($pos)"
Seeks through the compressed bitstream to the offset specified by $pos in raw bytes. Returns 0 on success.
"sample_seek ($pos)"
Seeks through the bitstream to the offset specified by $pos in pcm samples. Returns 0 on success.
"time_seek ($pos, [$page])"
Seeks through the bitstream to the offset specified by $pos in seconds. Returns 0 on success.
"bitrate ([$stream])"
Returns the average bitrate for the specified logical bitstream. If $stream is left out or set to -1, the average bitrate for the entire
stream will be reported.
"time_total ([$stream])"
Returns the total number of seconds in the bitstream.
"raw_tell ()"
Returns the current offset in bytes.
"time_tell ()"
Returns the current offset in seconds. - NOT YET IMPLEMENTED
REQUIRES

Hi all,
I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
