io_uring_register_clock(3) liburing Manual io_uring_register_clock(3)
io_uring_register_clock - set clock source for event waiting
#include <liburing.h>
int io_uring_register_clock(struct io_uring *ring,
struct io_uring_clock_register *arg);
The io_uring_register_clock(3) function registers which clock
source should be used by io_uring, when an application waits for
event completions. The ring argument should point to the ring in
question, and the arg argument should be a pointer to a struct
io_uring_clock_register .
The arg argument must be filled in with the appropriate
information. It looks as follows:
struct io_uring_clock_register {
__u32 clockid;
__u32 __resv[3];
};
The clockid field must contain the clock source, with valid
sources being:
CLOCK_MONOTONIC
a nonsettable system-wide clock that represents monotonic
time.
CLOCK_BOOTTIME
A nonsettable system-wide clock that is identical to
CLOCK_MONOTONIC , except that is also icnludes any time
that the system is suspended.
See clock_gettime(3) for more details.
The __resv fields must be filled with zeroes.
Available since 6.12.
On success io_uring_register_clock(3) returns 0. On failure it
returns -errno.
