Certainly! In C++, the equivalent to Python's time.time() for obtaining the current time in Linux can be achieved using the ctime header and the clock_gettime function. The clock_gettime function provides high-resolution timing information, and we can use it to get the current time in seconds since the epoch.
Here's a simple tutorial with a code example:
Let's break down the key parts of the code:
#include ctime: This header provides functionality for working with time.
clock_gettime(CLOCK_REALTIME, ¤tTime): This function is used to get the current time. The CLOCK_REALTIME flag specifies the system-wide clock measuring real-time. The result is stored in the currentTime structure.
currentTime.tv_sec and currentTime.tv_nsec: These fields of the timespec structure contain the seconds and nanoseconds, respectively.
getCurrentTimeInSeconds: This function encapsulates the process of obtaining the current time in seconds. It returns -1.0 on error.
main function: The main function demonstrates how to use getCurrentTimeInSeconds to obtain and print the current time in seconds.
Compile and run the C++ program, and you should see the current time in seconds since the epoch.
