SYNOPSIS    [Toc]    [Back]

     portstat

DESCRIPTION    [Toc]    [Back]

     portstat is a very	simple program which dumps the status of all the
     currently open audio ports	on a system.

     For each open port, it prints, in order: "port," the name of the port as
     passed to ALopenport; "pid," the ID of the	process	that opened the	port;
     "rbid," the internal ID of	the sample queue; "AL v," the version of the
     Audio Library which was used to open the port; "type," the	type of	the
     port (input or output); "nchans," the number of channels in the port's
     sample queue; "filled," the number	of samples currently in	the queue;
     "nlocs," the total	number of locations in the queue (possibly including
     an	extra location); and "errcnt," a count of the number of	overflows or
     underflows	which have occurred on the port	since it was opened.

     Note that portstat	does not work on Indigo	and Indigo R4K systems.
