UI::Util::File::File | ( | std::string const & | name, |
int | flags = O_CREAT | O_WRONLY , |
||
mode_t | mode = S_IRUSR | S_IWUSR , |
||
bool | closeFd = true |
||
) |
Constructor.
name | Path to the file to open |
flags | As in open(2) |
mode | As in open(2) |
closeFd | Whether to call close(2) in destructor |
This constructor takes a file name, will try to open the file using open(2). Arguments to open(2) can be given optionally, and have reasonable defaults.
OPEN_ERR will be thrown if the file could not be created via open(2).

fd | Already opened file descriptor |
closeFd | Whether to call close(2) in destructor |
This constructor takes an already opened file descriptor.
