atomic_bits(3c)

Standard C Library Functions                                   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);

DESCRIPTION
       The atomic_set_long_excl() and atomic_clear_long_excl() functions  per‐
       form  an  exclusive  atomic  bit  set or clear operation on target. The
       value of bit specifies the number of the bit to be modified within tar‐
       get. 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.
