* don't set mode in sio_setpar(), already done at initializationratchov2009-05-161-2/+1

* add a new ``hello'' message to aucat protocol useful to work onratchov2009-05-161-5/+25

* fix style to make future diffs contain functional changes onlyratchov2009-05-161-58/+58

* in aucat_getpar() and aucat_getcap(), initialize the message to sendratchov2009-05-161-3/+3

* replace s/sa/sio/, left from when libsa was renamed to libsndioratchov2009-05-151-27/+27

* if DEBUG is defined, use a global debug level ratherratchov2009-05-151-17/+17
| | | | than a per-stream debug level. No behaviour change.
* after the STOP message is sent, move the receiver to the RMSG stateratchov2009-02-251-3/+5
| | | | | | | only if it's in the IDLE state, otherwise in some rare cases a data chunk may be interpreted as a message, causing the connection to be dropped. ok deraadt
* in aucat_stop(), after the STOP message was send, put the receiverratchov2009-02-181-1/+3
| | | | | | in ``waiting state'', otherwise the ACK message will be skipped, and the other functions not expecting ACKs might be confused by the ACK.
* Programs have no direct access do the device file descriptor. So, ifratchov2009-02-041-1/+5
| | | | | | | | the programs calls execvp(2), the new image can't use the device, which stays open, so other programs get EBUSY. Set the close-on-exec flag to avoid this. ok jakemsr
* in server mode, create /tmp/aucat-userid/ directory withratchov2009-02-031-3/+9
| | | | | | | | | | | | permissions 0700, and create sockets in it. This prevents one local user to eavesdrop or disturb audio programs of other users. if you're using the ``-s socket'' option with an absolute path as argument, please update it to use a socket name. requested by many, bits from jakemsr and otto ok jakemsr
* make all private functions staticratchov2009-01-101-31/+31

* when polling aucat(1) socket, don't set the POLLIN bit if weratchov2008-12-271-2/+2
| | | | | don't expect messages. Avoids busy loops in programs calling poll(2) on a stopped device.
* when using the aucat(1) backend, don't mask the POLLHUP bitratchov2008-12-271-2/+2
| | | | | even if the device is not started yet. This way, if the server is killed programs can notice it.
* fix more spelling errors and typos,ratchov2008-12-211-4/+4
| | | | from Thomas Pfaff <tpfaff(at)@tp76.info>, thanks
* stop using stderr in the library, wrap all diagnostic fprintfsratchov2008-12-171-16/+16
| | | | | | so they are visible only when the DEBUG macro is #defined and SIO_DEBUG env. variable is set. requested by many, discussed with jakemsr
* fix spell errors, from Thomas Pfaff <tpfaff(at)tp76.info>, thanks!ratchov2008-12-171-3/+3

* add a writable ``appbufsz'' field to the sa_par structure, containingratchov2008-12-171-2/+3
| | | | | | | | the program-part of the buffer size, ie the part that is subject to underruns. Useful for apps like cdio(1) that don't have their own rings, or to apps that have a minimum ring size constraint. Setting the ``bufsz'' parameter becomes deprecated. ok jakemsr
* allow aucat to run as server in play-only and record-only mode, soratchov2008-11-171-11/+18
| | | | | it can be used on play-only, record-only and half-duplex devices. ok jakemsr
* when the aucat backend is used, sio_revents(3) should return POLLHUPratchov2008-11-161-1/+3
| | | | if the connection to the server is lost.
* expose a volume knob in the sndio API: add sio_setvol(3) andratchov2008-11-111-42/+90
| | | | | | | sio_onvol(3) functions. The audio(4) backend tries to use the inputs.dac, outputs.dac, outputs.output and outputs.master controls (in this order). Add a sample file in regress/lib/libsndio/vol/vol.c
* rename libsa to libsndioratchov2008-10-271-0/+528
