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.
The documentation for this class was generated from the following file:
