Detailed Description

Represents the result of a call to directory_iterator::status().

This is a subset of the information returned by a regular sys::fs::status() call, and represents the information provided by Windows FileFirstFile/FindNextFile.

Member Function Documentation

◆ getGroup()

uint32_t llvm::sys::fs::basic_file_status::getGroup ( ) const

◆ getLastAccessedTime()

TimePoint llvm::sys::fs::basic_file_status::getLastAccessedTime ( ) const

The file access time as reported from the underlying file system.

Also see comments on getLastModificationTime() related to the precision of the returned value.

Referenced by copyAccessAndModificationTime().

◆ getLastModificationTime()

TimePoint llvm::sys::fs::basic_file_status::getLastModificationTime ( ) const

The file modification time as reported from the underlying file system.

The returned value allows for nanosecond precision but the actual resolution is an implementation detail of the underlying file system. There is no guarantee for what kind of resolution you can expect, the resolution can differ across platforms and even across mountpoints on the same machine.
