NETAUDIO(3) 185
i
communicates directly with the DAT-Link to temporarily free the DAT-Link device.
nt NAResumeServer(unit)
int unit;
This convenience routines resumes the NetAudio server previously paused using
i
NAPauseServer().
nt NAWrite(port,buffer,buflen)
c
NAport ∗port;
onst char ∗buffer;
int buflen;
Write samples to the NetAudio server and ultimately to the DAT-Link device. A data connec-
s
tion to the server must be opened using NAOpenData() before using this routine. Samples
hould be stored in buffer as 16 bit shorts with the most-significant-byte first. Stereo data
f
d
should be interleaved starting with the left channel. Buflen indicates the number of bytes o
ata to transfer. NAWrite() will always write the requested number of bytes unless a transfer
w
error occurs such as a DAT-Link underrun, in which case the number of bytes actually written
ill be returned. A -1 return value indicates that the data channel was not open when
i
NAWrite() was called.
nt NARead(port,buffer,buflen)
c
NAport ∗port;
har ∗buffer;
int buflen;
Read samples from the NetAudio server and ultimately from the DAT-Link device. A data
-
p
connection to the server must be opened using NAOpenData() before using this routine. Sam
les will be stored in buffer as 16 bit shorts with the most-significant-byte first. Stereo data
a
t
will be interleaved starting with the left channel. Buflen indicates the number of bytes of dat
o transfer. Note that NARead() may read less than the requested number of bytes (but at least
s
one byte), even if no error has occurred. This is consistent with the definition of the read(2)
ystem call. A return value of 0 indicates that a transfer error has occurred, while a -1 return

value indicates that the data channel is not open for reading.
