Constructor & Destructor Documentation

virtual input_catenate::~input_catenate ( ) [virtual]

The destructor.

input_catenate::input_catenate	(	input	deeper[],
		size_t	ndeeper,
		bool	close_on_close
	)

The constructor.

input_catenate::input_catenate ( ) [private]

The default constructor. Do not use.

input_catenate::input_catenate ( const input_catenate & arg ) [private]

The copy constructor. Do not use.

Member Function Documentation

off_t input_catenate::ftell_inner ( ) [virtual]

The ftell_inner method is used to determine the unbuffered current position within the input.

Implements input_ty.

bool input_catenate::is_remote ( ) const [virtual]

The is_remote method is used to determine whether or not an input stream is from a local file or a remote source. This is only intended to be a generally informative thing, to provide information to the user, it isn't (and can't be) utterly precise.

Reimplemented from input_ty.

void input_catenate::keepalive ( ) [virtual]

The keepalive method is used to set the SO_KEEPALIVE socket option, if the file is a socket. Does nothing otherwise.

Reimplemented from input_ty.

off_t input_catenate::length ( ) [virtual]

The length method is used to determine the length of the input. May return -1 if the length is unknown.

Implements input_ty.

nstring input_catenate::name ( ) [virtual]

The name method is used to determine the name of the input.

Implements input_ty.

input_catenate& input_catenate::operator= ( const input_catenate & arg ) [private]

The assignment operator. Do not use.

ssize_t input_catenate::read_inner	(	void *	data,
		size_t	nbytes
	)		`[virtual]`

The read_inner method is used to read unbuffered data from the given input stream. At most nbytes bytes will be read into data. The number of bytes actually read will be returned. At end-of-file, a value <= 0 will be returned, and data will be unchanged. All file read errors or format errors are fatal, and will cause the method to not return.
