2009-05-16don't set mode in sio_setpar(), already done at initializationAlexandre Ratchov
2009-05-16add a new ``hello'' message to aucat protocol useful to work onAlexandre Ratchov
future aucat extentions. No functional changes.
2009-05-16fix style to make future diffs contain functional changes onlyAlexandre Ratchov
2009-05-16in aucat_getpar() and aucat_getcap(), initialize the message to sendAlexandre Ratchov
with AMSG_INIT(), rather than the reply we expect.
2009-05-15cleanup forgotten calls to exit(3)Alexandre Ratchov
2009-05-15replace s/sa/sio/, left from when libsa was renamed to libsndioAlexandre Ratchov
2009-05-15in headers, macro definitions come first, prototypes come nextAlexandre Ratchov
2009-05-15if DEBUG is defined, use a global debug level ratherAlexandre Ratchov
than a per-stream debug level. No behaviour change.
2009-05-15describe sio_getcap(), sio_pollfd() and sio_setvol() retrurn valuesAlexandre Ratchov

2009-04-21no need to install includes from here anymoreTheo de Raadt
2009-04-21move src/lib/libsndio/sndio.h into src/include where other includeAlexandre Ratchov
files leave. requested by deraadt@, ok miod@
2009-04-13protypes in sndio.h make reference to struct pollfd; applicationsAlexandre Ratchov
that don't use sys/poll.h, wont compile with gcc2. Fix this by declaring the pollfd structure spotted by and ok deraadt
2009-02-26don't use ``hdl->filling'' flag uninitializedAlexandre Ratchov
ok deraadt
2009-02-25after the STOP message is sent, move the receiver to the RMSG stateAlexandre Ratchov
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
2009-02-18in aucat_stop(), after the STOP message was send, put the receiverAlexandre Ratchov
in ``waiting state'', otherwise the ACK message will be skipped, and the other functions not expecting ACKs might be confused by the ACK.
2009-02-09ignore evironment variables if the program is setuid or setgidAlexandre Ratchov
explained by deraadt, ok miod, ok millert
2009-02-04update the default socket paths, to reflect recent aucat changesAlexandre Ratchov
2009-02-04explain that it's ok if we get a slightly different rate thanAlexandre Ratchov
the one we asked for, from Thomas Pfaff <tpfaff(at)tp76.info> with tweaks from jmc@
2009-02-04Programs have no direct access do the device file descriptor. So, ifAlexandre Ratchov
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
2009-02-03in server mode, create /tmp/aucat-userid/ directory withAlexandre Ratchov
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
2009-01-21fix bugs section: clarify that sio_start() and sio_stop() shouldAlexandre Ratchov
not be used if blocking is not desirable.
2009-01-21explain what ``frame'' does meanAlexandre Ratchov
from Thomas Pfaff <tpfaff(at)tp76.info>, thanks! ok jmc
2009-01-21make declarations "C" to allow c++ code to compileAlexandre Ratchov
discussed with espie@, ok jakemsr@ and millert@
2009-01-17cleanup: remove prototypes of inexistent functions, move few privateAlexandre Ratchov
functions into private header file. suggested by espie@
2009-01-12replace s/routine/function/, as other manuals doAlexandre Ratchov
from Thomas Pfaff <tpfaff(at)tp76.info>, thanks! ok jmc@

2009-01-08oops, i messed up tim's patch; correction from Tim van der MolenJason McIntyre
2009-01-08a little macro cleanup; from Tim van der MolenJason McIntyre
2008-12-27when polling aucat(1) socket, don't set the POLLIN bit if weAlexandre Ratchov
don't expect messages. Avoids busy loops in programs calling poll(2) on a stopped device.
2008-12-27when using the aucat(1) backend, don't mask the POLLHUP bitAlexandre Ratchov
even if the device is not started yet. This way, if the server is killed programs can notice it.
2008-12-21remove mixer bits from the audio(4) backend of libsndio, it's notAlexandre Ratchov
possible to get them right in the current state of the mixer. discussed with jakemsr
2008-12-21fix more spelling errors and typos,Alexandre Ratchov
from Thomas Pfaff <tpfaff(at)@tp76.info>, thanks
2008-12-17stop using stderr in the library, wrap all diagnostic fprintfsAlexandre Ratchov
so they are visible only when the DEBUG macro is #defined and SIO_DEBUG env. variable is set. requested by many, discussed with jakemsr

2008-12-17fix spell errors, from Thomas Pfaff <tpfaff(at)tp76.info>, thanks!Alexandre Ratchov
2008-12-17add a writable ``appbufsz'' field to the sa_par structure, containingAlexandre Ratchov
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
2008-11-20make both aucat(1) and audio(4) backends use the AUDIODEVICE envAlexandre Ratchov
variable to determine the socket or the device to use. Allow choosing the when aucat(1) is used too. Noticed and tested by naddy@
2008-11-20while setting the block size, try smaller blocks half of the retries andAlexandre Ratchov
larger blocks the other half. That's because shrinking the block size may not be the right direction to go to find a common block size for play and record.
2008-11-17occures -> occurs;Jason McIntyre
2008-11-17allow aucat to run as server in play-only and record-only mode, soAlexandre Ratchov
it can be used on play-only, record-only and half-duplex devices. ok jakemsr
2008-11-16document that sio_revents() can return POLLHUPAlexandre Ratchov
2008-11-16when the aucat backend is used, sio_revents(3) should return POLLHUPAlexandre Ratchov
if the connection to the server is lost.
2008-11-11tweak previous;Jason McIntyre
2008-11-11expose a volume knob in the sndio API: add sio_setvol(3) andAlexandre Ratchov
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
2008-11-09typos; ok ratchov@ jmc@Christian Weisgerber
2008-11-09if the device is not started, make sio_pollfd() pass 0 events bitmapAlexandre Ratchov
to the backend to avoid reporing the device as writable when it's stopped. Solves 100% CPU usage of apps poll()ing a stopped device.
2008-11-09sio_revents() should return 0 poll events if the device isn't startedAlexandre Ratchov
2008-11-07expose the block size in the sndio API by making par->round writableAlexandre Ratchov
and thus remove the ugly rate <-> block-size table from sio_setpar(3). Handle the block size negociation in aucat(1), since it has few constrains the code is overally simpler. ok jakemsr@, major crank suggested by deraadt@
2008-10-30only few (frequency, blocksize) pairs are compatible with both resamplingAlexandre Ratchov
and block based audio i/o (arithmetic constraints). For now round the frequency to a supported one, (ie 8kHz, 11.025kHz, 12kHz multiple), and get the the block size from a table. fixes problem reported by Robert <robert _at_ openbsd.pap.st> ok jakemsr
