#include int main() { timespec ts; // clock_gettime(CLOCK_MONOTONIC, &ts); // Works on FreeBSD clock_gettime(CLOCK_REALTIME, &ts); // Works on Linux }
Code Explanation:
Including Necessary Library
The #include <time.h>
directive is used to include the necessary library for time-related functions.
Defining the Main Function
The int main()
function serves as the entry point for the program.
Declaring a timespec Variable
The line timespec ts;
declares a variable ts
of type timespec
.
Obtaining the Monotonic Time (FreeBSD)
The line // clock_gettime(CLOCK_MONOTONIC, &ts);
is a commented-out call to the clock_gettime
function with CLOCK_MONOTONIC
as the clock ID. This particular call works on FreeBSD.
Obtaining the Realtime Clock Time (Linux)
The line clock_gettime(CLOCK_REALTIME, &ts);
calls the clock_gettime
function with CLOCK_REALTIME
as the clock ID. This call works on Linux.
