c++ usleep()
The usleep() function in C++ is used to suspend the execution of the program for a specified number of microseconds. It is part of the unistd.h header file, which provides access to various system functions.
Here is an explanation of each step involved in using usleep():
Include the necessary header file: To use usleep(), you need to include the unistd.h header file at the beginning of your program. You can do this by adding the following line of code: #include
Declare the usleep() function: Before using the usleep() function, you need to declare it. The function declaration should match the following format: void usleep(useconds_t microseconds);
Call the usleep() function: To pause the program execution for a specific number of microseconds, you can call the usleep() function. The function takes a single argument, which specifies the duration in microseconds. For example, to pause the program for 1 second (1,000,000 microseconds), you can use the following code: usleep(1000000);
Resume program execution: After the specified number of microseconds have elapsed, the program execution resumes from where it left off.
It's important to note that usleep() is a deprecated function in C++11 and later versions. It is recommended to use the std::this_thread::sleep_for() function from the
