I\'m running a Xenomai real time thread that sometimes needs to call gettimeofday(), in order to find out what the current time is according to ptpd.
I\'m attempting to monitor system time elapsed across multiple applications and data paths via gettimeoday and localtime. In this example, I want to grab the system time (microsecond percision) right
I\'m trying to pass pointers to two struct timevals to a function that would output the elapsed time between the 开发者_JAVA百科two in a C program. However, even if I dereference these pointers, nvcc
I\'m trying to write a simple function in C that would calculate the difference between two moments in nanoseconds. To do this, I thought of using the function gettimeofday, which updates the given st
When I do: date system call on freeBSD, does it internally use gettimeofday ? Another que: how do I know where the code of \"date\" command sitting开发者_StackOverflow社区 on the system?
i am measuring physical time between two events like this: #include <time.h> #include <sys/time.h>
I do not really wish to profile because I was wanting to do many different small benchmarks on different simple functions. For the life of me I cannot find a way to record the amoun开发者_StackOverflo
Update: fixed delta calculations in code, still the issue remains Folks, could you please explain why I\'m getting very strange results from time to time using the following code:
I want to measure the running times o开发者_Go百科f selected loops in a C program so as to see what percentage of the total time for executing the program (on linux) is spent in these loops. I should
