Member Function Documentation

attach() [1/2]

void gzifstream::attach	(	int	fd,
		std::ios_base::openmode	mode = std::ios_base::in
	)

Attach to already open gzipped file.

Parameters

fd	File descriptor.
mode	Open mode flags (forced to contain ios::in).

Stream will be in state good() if attach succeeded; otherwise in state fail().

Definition at line 409 of file bloaty/third_party/zlib/contrib/iostream3/zfstream.cc.

attach() [2/2]

void gzifstream::attach	(	int	fd,
		std::ios_base::openmode	mode = std::ios_base::in
	)

Attach to already open gzipped file.

Parameters

fd	File descriptor.
mode	Open mode flags (forced to contain ios::in).

Stream will be in state good() if attach succeeded; otherwise in state fail().

close() [1/2]

void gzifstream::close

(

)

Close gzipped file.

Stream will be in state fail() if close failed.

Definition at line 420 of file bloaty/third_party/zlib/contrib/iostream3/zfstream.cc.

close() [2/2]

void gzifstream::close

(

)

Close gzipped file.

Stream will be in state fail() if close failed.

is_open() [1/2]

bool gzifstream::is_open ( )

inline

Check if file is open.

Returns

True if file is open.

Definition at line 270 of file bloaty/third_party/zlib/contrib/iostream3/zfstream.h.

is_open() [2/2]

bool gzifstream::is_open ( )

inline

Check if file is open.

Returns

True if file is open.

Definition at line 270 of file zlib/contrib/iostream3/zfstream.h.

open() [1/2]

void gzifstream::open	(	const char *	name,
		std::ios_base::openmode	mode = std::ios_base::in
	)

Open gzipped file.

Parameters

name	File name.
mode	Open mode flags (forced to contain ios::in).

Stream will be in state good() if file opens successfully; otherwise in state fail(). This differs from the behavior of ifstream, which never sets the state to good() and therefore won't allow you to reuse the stream for a second file unless you manually clear() the state. The choice is a matter of convenience.

open() [2/2]

void gzifstream::open	(	const char *	name,
		std::ios_base::openmode	mode = std::ios_base::in
	)

Open gzipped file.

Parameters

name	File name.
mode	Open mode flags (forced to contain ios::in).

Stream will be in state good() if file opens successfully; otherwise in state fail(). This differs from the behavior of ifstream, which never sets the state to good() and therefore won't allow you to reuse the stream for a second file unless you manually clear() the state. The choice is a matter of convenience.

rdbuf() [1/2]

gzfilebuf* gzifstream::rdbuf ( ) const

inline

Obtain underlying stream buffer.

Definition at line 262 of file zlib/contrib/iostream3/zfstream.h.

rdbuf() [2/2]

gzfilebuf* gzifstream::rdbuf ( ) const

inline
