And out of > curiousity, what is the function of this particular ioctl?a It's not so much the emulation as the current sound drivers that are the issue here. It's defined in as : #define SNDCTL_DSP_GETTRIGGER _IOR ('P',16, int) #define SNDCTL_DSP_SETTRIGGER _IOW ('P',16, int) The OSS lite beta driver may support it, but it's known to be buggy. > Randall -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
