# FSSyncFlags

Behavior flags for use with synchronization calls.

## Declaration

```swift
enum FSSyncFlags
```

## Overview

Overview These values are based on flags defined in mount.h. Since there are system-defined flags that are valid in the kernel but not in FSKit, this type defines its members as options rather than use an enumeration.
