Changeset 9902

Timestamp:

Mar 5, 2003, 3:49:04 PM (22 years ago)

Author:

sandervl

Message:

waveoutGetPosition: return 0 if stream is not active (DART); waveinGetPosition: return 0 if stream is not active (DART); Don't print a warning for CALLBACK_NULL callbacks; Added ODIN_waveInSetFixedBuffers, renamed SetFixedWaveBufferSize to ODIN_waveOutSetFixedBuffers. Used to tell WINMM to use the waveOutWrite buffer size for the DART buffers
