Question

I am basically trying to get the time with

struct timeval tv = { };
gettimeofday(&tv, NULL);

And it works. The problem is that the function that is going to accept as an argument the time is of type const char*

So i did

const char *time;
time = &tv.tv_sec;

The problem is, that tv.tv_sec is of type time_t and i need to plug it in

const char *time

to pass it on to the function that needs const char*

How do i do it? Placing an integer into a const char*
I’ve tried some simple ways of casting it, however i am not that experienced with C

To format an integer as a string you should use snprintf.

For example:

char resultString[64];

snprintf(resultString, sizeof(resultString), "Current time : %d", tv.tv_sec);
