Member Function Documentation

UnixSocket * ola::io::UnixSocket::OppositeEnd

(

)

Fetch the other end of the unix socket.

Returns

A new UnixSocket or NULL if the socket wasn't initialized correctly. Its an error to call this more than once. Ownership of the returned UnixSocket is transferred to the caller.

DescriptorHandle ola::io::UnixSocket::ReadDescriptor ( ) const

inlinevirtual

Returns the read descriptor for this socket.

Returns

the DescriptorHandle for this descriptor.

Implements ola::io::ReadFileDescriptor.

DescriptorHandle ola::io::UnixSocket::WriteDescriptor ( ) const

inlinevirtual

Returns the write descriptor for this socket.

Returns

the DescriptorHandle for this descriptor.

Implements ola::io::WriteFileDescriptor.
