If you've ever used ddi_get_pid() to return the process's PID, you'll find the
function below rather handy:
char *
ddi_get_proc_name (void) /* Return the command name of the current thread */
{
return ttoproc (curthread)->p_user.u_comm;
}
This function will return the name of the process (or program) that
ddi_get_pid() will return.
If you've ever user mixertool while running an audio app, you can only see the
PID of the process. Using our little kernel function, you can also get the name
of the process that was currently playing.
We use it in our Open Sound drivers to show what process (and it's PID) is
currently accessing the particular OSS device.
We'd like to request a formal inclusion of this function into Open Solaris.
