Gzipped file output stream class.
This class implements ofstream for gzipped files. Seeking and putback is not supported yet.
Definition at line 80 of file zfstream.h.
| gzofstream::gzofstream | ( | ) |
|
virtual |
| gzofstream::gzofstream | ( | ) |
|
explicit |
Construct stream on gzipped file to be opened.
| name | File name. |
| mode | Open mode flags (forced to contain ios::out). |
|
explicit |
Construct stream on already open gzipped file.
| fd | File descriptor. |
| mode | Open mode flags (forced to contain ios::out). |
| void gzofstream::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 gzofstream::close | ( | ) |
Close gzipped file.
Stream will be in state fail() if close failed.
|
inline |
Check if file is open.

References gzfilebuf::is_open().
| void gzofstream::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.

inline |
Obtain underlying stream buffer.
