Gzipped file output stream class.
This class implements ofstream for gzipped files. Seeking and putback is not supported yet.

gzofstream | ( | const char * | name, |
std::ios_base::openmode | mode = std::ios_base::out |
||
) | [explicit] |
Construct stream on gzipped file to be opened.
name | File name. |
mode | Open mode flags (forced to contain ios::out). |
gzofstream | ( | int | fd, |
std::ios_base::openmode | mode = std::ios_base::out |
||
) | [explicit] |
Construct stream on already open gzipped file.
fd | File descriptor. |
mode | Open mode flags (forced to contain ios::out). |
void attach | ( | int | fd, |
std::ios_base::openmode | mode = std::ios_base::out |
||
) |
Attach to already open gzipped file.
fd | File descriptor. |
mode | Open mode flags (forced to contain ios::out). |
Stream will be in state good() if attach succeeded; otherwise in state fail().
void close | ( | ) |
Close gzipped file.
Stream will be in state fail() if close failed.
Reimplemented from gzfilestream_common.
bool is_open | ( | ) | [inline] |
void open | ( | const char * | name, |
std::ios_base::openmode | mode = std::ios_base::out |
||
) |
Open gzipped file.
name | File name. |
mode | Open mode flags (forced to contain ios::out). |
Stream will be in state good() if file opens successfully; otherwise in state fail(). This differs from the behavior of ofstream, 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.
gzfilebuf* rdbuf | ( | ) | const [inline] |
Obtain underlying stream buffer.
