12/18/2019 · int usleep( useconds_t useconds ); Where useconds_t is of type unsigned integer. It returns an integer; 0 if successful, -1 if unsuccessful. It can accept anywhere from 0 to 999999 microseconds. Here are some examples of coding the API in CLLE, RPGLE, and C. In these examples, the job is delayed for 500,000 microseconds, or 0.5 seconds.
In usleep function 1000000 = 1sec. Try to change your code accordingly. So: usleep(1000000) // generates 1 second delay, DESCRIPTION. The usleep () function suspends the calling thread until either the number of real-time microseconds specified by period has elapsed or a signal is delivered to the calling thread. The suspension time may be longer than requested because the argument value is rounded up to an integer multiple of the sleep resolution, or due to the scheduling of other activity by the system.
C++ (Cpp) sys_timer_ usleep – 16 examples found. These are the top rated real world C++ (Cpp) examples of sys_timer_ usleep extracted from open source projects. You can rate examples to help us improve the quality of examples .
The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers. RETURN VALUE top The usleep() function returns 0 on, C programming language provides sleep() function in order to wait for a current thread for a specified time.slepp() function will sleep given thread specified time for the current executable. Of course, the CPU and other processes will run without a problem. Include unistd.h Library In Linux. sleep() function is provided by unistd.h library which is a short cut of Unix standard library.
Given below is an example to demonstrate the usleep function. #include #include #include using namespace std; int main() { cout << Hello ; cout.flush(); usleep(10000); cout << World; cout << endl; return 0; } Output: Hello World, 9/29/2009 · usleep is not a very accurate form of sleep in C / C++ . From the man page: The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers. nanosleep, on the other hand, is much more accurate. The following code will perform a sleep for 100 miliseconds using nanosleep:
