FUTEX_LOCK_PI2(2const)                             FUTEX_LOCK_PI2(2const)

NAME         top

       FUTEX_LOCK_PI2 - lock a priority‐inheritance futex

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #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         top

       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         top

       See FUTEX_LOCK_PI(2const).

ERRORS         top

       See FUTEX_LOCK_PI(2const).

STANDARDS         top

       Linux.

HISTORY         top

       Linux 5.14.

SEE ALSO         top
