18d252bbfe Detect Win XP and Win 2K properly when determining latency. 2002-04-19 18:31:54 +00:00

baefbbdc4a Change sine generation method so that sine waves don't line up with PA buffers. 
This was causing it to appear that audio was OK even when buffers were dropped..

687dfcbe4e Fixed bug where I was calling the wrong function to calculate 
the minimum number of user buffers. This resulted in a too conservative,
ie. too high, latency.

b47db27181 Added paInt16, paInt8, format using new "pa_common/pa_convert.c" file. 
Return error if opened in mono mode cuz not supported.
Add support for Pa_GetCPULoad();
Fixed timestamp in callback and Pa_StreamTime() (Thanks n++k for the advice!)
Check for invalid sample rates and return an error.
Check for getenv("PA_MIN_LATEWNCY_MSEC") to set latency externally.
Better error checking for invalid channel counts and invalid devices.

7e73ac614d Fixed the nonblocking open - now it tries to open each device in 
nonblocking mode, and if that succeeds, closes it and opens it
again in blocking mode - and added a new Pa_StreamTime
implementation that uses SNDCTL_DSP_GET[I/O]PTR.

5f6b6644dd Added O_NONBLOCK to all open() calls, so that PortAudio 
does not hang if the device is in use by another program.
