FUTEX_LOCK_PI2(2const)                                  FUTEX_LOCK_PI2(2const)

NAME
       FUTEX_LOCK_PI2 - lock a priority-inheritance futex

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <linux/futex.h>  /* Definition of FUTEX_* constants */
       #include <sys/syscall.h>  /* Definition of SYS_* constants */
       #include <unistd.h>

       long syscall(SYS_futex, uint32_t *uaddr, FUTEX_LOCK_PI2, 0,
                    const struct timespec *timeout);

DESCRIPTION
       This operation is the same as FUTEX_LOCK_PI(2const), except that the
       clock against which timeout is measured is selectable.

       By default, the (absolute) timeout specified in timeout is measured
       against the CLOCK_MONOTONIC clock.

RETURN VALUE
       See FUTEX_LOCK_PI(2const).

ERRORS
       See FUTEX_LOCK_PI(2const).

STANDARDS
       Linux.

HISTORY
       Linux 5.14.
