Detailed Description

The input_stdin class is used to represent an input source which reads from the standard input.

Constructor & Destructor Documentation

virtual input_stdin::~input_stdin

(

)

[virtual]

The destructor.

input_stdin::input_stdin

(

)

The default constructor.

input_stdin::input_stdin

(

const input_stdin &

arg

)

[private]

The copy constructor. Do not use.

---

Member Function Documentation

off_t input_stdin::ftell_inner

(

)

[virtual]

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

Implements input_ty.

void input_stdin::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_stdin::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_stdin::name

(

)

[virtual]

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

Implements input_ty.

input_stdin& input_stdin::operator=

(

const input_stdin &

arg

)

[private]

The default constructor. Do not use.

ssize_t input_stdin::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.

Parameters:

data	Where to put the results of the read.
nbytes	The maximum number of bytes to read.

Returns:

The actual number of bytes read, or zero for end-of-file.

Implements input_ty.
