Detailed Description

Close a file handle.

Definition at line 129 of file request-fs.hpp.

Member Function Documentation

handle()

file uv::fs::close::handle ( ) const

inlinenoexcept

The file which this close request has been running on.

It is guaranteed that it will be a valid instance at least within the request callback.

Definition at line 180 of file request-fs.hpp.

run()

int uv::fs::close::run ( file &  _file )

inline

Run the request. Close a _file handle.

If the _file is in reading state being put in by io::read_start() function, the request calls io::read_stop() for the _file.

See also

libuv API documentation: uv_fs_close().

Linux: close().

Note

If the request callback is empty (has not been set), the request runs synchronously.
