NAME
     atomic_bits, atomic_set_long_excl, atomic_clear_long_excl  -
     atomic set and clear bit operations

SYNOPSIS
     #include 

     int atomic_set_long_excl(volatile ulong_t *target, uint_t bit);


     int atomic_clear_long_excl(volatile ulong_t *target, uint_t bit);


DESCRIPTION
     The  atomic_set_long_excl()   and   atomic_clear_long_excl()
     functions  perform  an  exclusive  atomic  bit  set or clear
     operation on target. The value of bit specifies  the  number
     of  the  bit to be modified within target. Bits are numbered
     from zero to one less than the maximum number of bits  in  a
     long.  If  the value of bit falls outside of this range, the
     result of the operation is undefined.

RETURN VALUES
     The  atomic_set_long_excl()   and   atomic_clear_long_excl()
     functions  return  0 if bit was successfully set or cleared.
     They return -1 if bit was already set or cleared.

ERRORS
     No errors are defined.
