Standard C Library Functions                        atomicor(3C)



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


     uint64t atomicor64nv(volatile uint64t *target, uint64t bits);


DESCRIPTION
     These functions enable the the bitwise OR  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:

     MT-Level                     MT-Safe

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.
