Declaration

- path:
The path to the file, device, or named socket to access.
Return Value

Discussion
The system sets the file pointer to the beginning of the file. You can’t write data to the returned file handle object. Use the readDataToEndOfFile() or readData(ofLength:) methods to read data from it.
When using this method to create a file handle object, the file handle owns its associated file descriptor and is responsible for closing it.
