Alternative of system() in c Linux to execute a terminal command of linux
 

I want to execute a terminal command of linux in C program. currently I am using system() function but I want to use any other as system() function is banned as per MISRA.

for ex, how to replace

system("hwclock --systohc --utc");

(I'm not really familiar with MISRA)
I assume in general you are not allowed to invoke external commands, so replacing system call is not a solution.
In such cases I would check the source code of hwclock, probably you will get some tips how to use that within your app.
