This operation is the same as
.BR FUTEX_LOCK_PI ,
except that the clock against which
.I timeout
argument.

has support for selectable clocks.

is measured is selectable.
By default, the (absolute) timeout specified in
.I timeout
is not NULL, the structure it points to specifies
an absolute timeout.
If
.I timeout
is NULL, the operation can block indefinitely.
.IP
is measured againt the
.B CLOCK_MONOTONIC
clock, but if the
.B FUTEX_CLOCK_REALTIME
flag is specified in
.IR futex_op ,
then the timeout is measured against the
.B CLOCK_REALTIME
clock.
