Detailed Description¶
This class is used to access non-reentrant date and time functions in the standard C library. The class has two purposes:- •
- 1 To be used internaly in CommonCpp's date and time classes to make them thread safe.
- •
- 2 To be used by clients as thread safe replacements to the standard C functions, much like Thread::sleep() represents a thread safe version of the standard sleep() function.
The class provides one function with the same name as its
equivalent standard function and one with another, unique name. For new
clients, the version with the unique name is recommended to make it easy to
grep for accidental usage of the standard functions. The version with the
standard name is provided for existing clients to sed replace their original
version.
Also note that some functions that returned pointers have been redone to take
that pointer as an argument instead, making the caller responsible for memory
allocation/deallocation. This is almost how POSIX specifies *_r functions
(reentrant versions of the standard time functions), except the POSIX
functions also return the given pointer while we do not. We don't use the *_r
functions as they aren't all generally available on all platforms yet.
