Detailed Description
Write text into file.
This class allows a comfortable output to a file only by using the elementary system calls open() / write() / close() and (optional) fsync(). The class is derived from OutputStream.
Constructor & Destructor Documentation
|
explicit |
Constructor.
Opens the file for writing using the system call open().
- Parameters
-
path Path to the output file
|
virtual |
Destructor.
Close the output file (using the system call close())
Member Function Documentation
| const char * FileOut::getPath | ( | ) |
Get path of the output file.
- Returns
- Path to output file (as defined in constructor)
|
static |
Number of output files which are currently opened (with this class)
- Returns
- Number of active files
|
overridevirtual |
Write the string to the open file.
The implementation should only use the system calls write() and fsync().
Implements OutputStream.
