Detailed Description

Wraps a Unix file descriptor. It's possible to get the file descriptor used by some classes (such as FileInputStream, FileOutputStream, and RandomAccessFile), and then create new streams that point to the same file descriptor.

java.io.FileDescriptor.FileDescriptor ( )

inline

Constructs a new invalid FileDescriptor.

Member Function Documentation

getInt()

final int java.io.FileDescriptor.getInt ( )

setInt()

final void java.io.FileDescriptor.setInt ( int  fd )

inline

Sets the int fd. It's highly unlikely you should be calling this. Please discuss your needs with a libcore maintainer before using this method. internal use only

sync()

void java.io.FileDescriptor.sync ( ) throws SyncFailedException

inline

Ensures that data which is buffered within the underlying implementation is written out to the appropriate device before returning.

valid()

boolean java.io.FileDescriptor.valid ( )

inline

Tests whether this

FileDescriptor 

is valid.
