pure virtual |
Flushes all buffered output to the stream.
true in case of success, or false in case of errors. Writes a number of bytes to the stream.
| buffer | The buffer from where to read the data. |
| size | The number of bytes to write. |
|
pure virtual |
Writes a zero-terminated string to the stream.
| str | The string to be written. Note that the writer does not add an extra newline character at the end. |
true in case of success, or false in case of errors.
