| 4 | \section{\class{wxFileOutputStream}}\label{wxfileoutputstream} | |
| 5 | ||
| 6 | This class represents data written to a file. There are actually | |
| 7 | two such groups of classes: this one is based on \helpref{wxFile}{wxfile} | |
| 8 | whereas \helpref{wxFFileInputStream}{wxffileinputstream} is based in | |
| 9 | the \helpref{wxFFile}{wxffile} class. | |
| 10 | ||
| 11 | Note that \helpref{wxFile}{wxfile} and \helpref{wxFFile}{wxffile} differ | |
| 12 | in one aspect, namely when to report that the end of the file has been | |
| 13 | reached. This is documented in \helpref{wxFile::Eof}{wxfileeof} and | |
| 14 | \helpref{wxFFile::Eof}{wxffileeof} and the behaviour of the stream | |
| 15 | classes reflects this difference, i.e. wxFileInputStream will report | |
| 16 | wxSTREAM\_EOF after having read the last byte whereas wxFFileInputStream | |
| 17 | will report wxSTREAM\_EOF after trying to read {\it past} the last byte. | |

18 | Related to EOF behavior, note that \helpref{SeekO()}{wxoutputstreamseeko} |
| 19 | can seek beyond the end of the stream (file) and will thus not return | |
| 20 | {\it wxInvalidOffset} for that. | |

| 41 | \func{}{wxFileOutputStream}{\param{const wxString\&}{ ofileName}} | |
| 42 | ||
| 43 | Creates a new file with {\it ofilename} name and initializes the stream in | |
| 44 | write-only mode. | |
| 45 | ||
| 46 | \func{}{wxFileOutputStream}{\param{wxFile\&}{ file}} | |
| 47 | ||
| 48 | Initializes a file stream in write-only mode using the file I/O object {\it file}. | |
| 49 | ||
| 50 | \func{}{wxFileOutputStream}{\param{int}{ fd}} | |
| 51 | ||
| 52 | Initializes a file stream in write-only mode using the file descriptor {\it fd}. | |

| cc81d32f | 64 | Returns true if the stream is initialized and ready. |
