atomic_clear_long_excl

atomic_bits(3C) 														   atomic_bits(3C)

NAME

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

SYNOPSIS

       #include <atomic.h>

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

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

       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.

       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.

       No errors are defined.
