gettimeofdayis a highly accurate time retrieval function in Linux based systems, which can be called from the C++ source code as well. The function was designed to get the time and timezone data, but the latter

Not having a new-line char at the end of file breaks .h files with the Sun WorkShop compiler and it breaks .cpp files on HP. Don't put extra top-level semi-colons in code Non-portable example: int A::foo() { }; This is another problem that seems to show up more on C++ than...
While most of the effort to date has focused on the library and projection, Kerr says the cppwinrt compiler deserves attention. “Developers really need to get their hands on this tool as it solves a lot of problems, from generating projections for different platforms or components, to ...
In addition to the gettimeofday function, another powerful tool for measuring elapsed time in C programming is the clock_gettime function. This function provides a higher resolution and more consistent interface for obtaining time information. The clock_gettime function is part of the <time.h> hea...
