NAME
     Pnice - change process priority for the current process

SYNOPSIS
     WORD Pnice( WORD delta );

DESCRIPTION
     Pnice changes the base process niceness for the current pro-
     cess  by  the  amount  delta.   Higher  levels  of  niceness
     correspond to decreased priority in scheduling, so  positive
     values  for  delta  cause  the  corresponding  process to be
     scheduled less often. Conversely, negative values for  delta
     cause the process priority to be increased.

RETURNS
     The (adjusted) process priority, as a 16 bit signed integer.
     0  is  the  default  priority; values greater than 0 are for
     higher priority processes  (ones  that  are  scheduled  more
     often), and values less than 0 are lower priority processes.

SEE ALSO

BUGS
     The scheduling algorithm is pretty weird, so  it's  hard  to
     predict exactly what effect process priorities have.
