ptr,
perform a logical
`and'
with the value
bits,
and store the result back to the variable referenced by
ptr
in an atomic fashion.
The
*_nv()
variants of these functions return the new value.
The 64-bit variants of these functions are available only on platforms
that can support atomic 64-bit memory access.
Applications can check for the availability of 64-bit atomic memory
operations by testing if the pre-processor macro
__HAVE_ATOMIC64_OPS
is defined.
