Member Function Documentation

off_t input_822wrap::ftell_inner

(

)

[virtual]

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

Implements input_ty.

bool input_822wrap::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_822wrap::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_822wrap::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_822wrap::name

(

)

[virtual]

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

Implements input_ty.

input_822wrap& input_822wrap::operator=

(

const input_822wrap &

arg

)

[private]

The assignment operator. Do not use.

ssize_t input_822wrap::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.

Field Documentation

int input_822wrap::column [private]

The column instance variable is used to remember the current column of the cursor position. Zero based.

Definition at line 78 of file 822wrap.h.

input& input_822wrap::deeper [private]

The deeper instance variable is used to remember the data source for this filter.

Definition at line 66 of file 822wrap.h.

off_t input_822wrap::pos [private]

The pos instance variable is used to remember the byte position withing this input stream.

Definition at line 72 of file 822wrap.h.
