Standard C Library Functions                       atomicand(3C)



     ulongt atomicandulongnv(volatile ulongt *target, ulongt bits);


     uint64t atomicand64nv(volatile uint64t *target, uint64t bits);


DESCRIPTION
     These functions enable the bitwise AND of bits to the  value
     stored in target to occur in an atomic manner.

RETURN VALUES
     The *nv() variants of these functions return the new  value
     of target.

ERORS
     No errors are defined.

ATRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:



     
           ATRIBUTE TYPE               ATRIBUTE VALUE       
    
     Interface Stability          Committed                   
    
     MT-Level                     MT-Safe                     
    


SEE ALSO
     atomicadd(3C),       atomicbits(3C),       atomiccas(3C),
     atomicdec(3C),        atomicinc(3C),        atomicor(3C),
     atomicswap(3C),       membarops(3C),        attributes(5),
     atomicops(9F)

NOTES
     The *nv() variants are substantially more expensive on some
     platforms  than  the  versions that do not return values. Do
     not use them unless you need to know the  new  value  atomi-
     cally.
