That answer makes no sense. There are tons of things that are provided
by the OS which a normal program can use, such as reading and writing
files, allocating memory, printing to stdout, etc.
The correct answer is: No, the C++ standard does not provide any
standard mechanism for file locking. For that you'll have to resort to
some external system-specific functions such as the ones provided by the
POSIX standard or your OS API.
