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.
- Note:
- 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. - Author:
