# zx_deadline_after

## NAME

<!-- Updated by update-docs-from-fidl, do not edit. -->

Convert a time relative to now to an absolute deadline.

## SYNOPSIS

<!-- Updated by update-docs-from-fidl, do not edit. -->

```c
#include <zircon/syscalls.h>

zx_time_t zx_deadline_after(zx_duration_t nanoseconds);
```

## DESCRIPTION

`zx_deadline_after()` is a utility for converting from now-relative durations
to absolute deadlines. If *nanoseconds* plus the current time is bigger than the
maximum value for `zx_time_t`, the output is clamped to **ZX_TIME_INFINITE**.

## RETURN VALUE

`zx_deadline_after()` returns the absolute time (with respect to **ZX_CLOCK_MONOTONIC**)
that is *nanoseconds* nanoseconds from now.

## ERRORS

`zx_deadline_after()` does not report any error conditions.

## EXAMPLES

```
// Sleep 50 milliseconds
zx_time_t deadline = zx_deadline_after(ZX_MSEC(50));
zx_nanosleep(deadline);
```
