_p_o_r_t_s_t_a_t 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.
