how to convert type clock_t value to char

I am using the value clock_t in my C program, and the related function clock(). The problem is that I need to display the value of clock_t variables and I can only do it in charcter type as I am displaying it in openGL with my own custom function for displaying which only takes char type string. Please help me.
Secondly what type of a function can I use to delay execution for some time. I have tried to used sleep and delay and have added the header file DOS.H. But the compiler still doesnt recognize the calls to sleep() or delay(). My program is in c++.

localtime(time_t*) returns the string that you probably want

sleep() is a unix function, and Sleep() is a Win32 API function. Neither are available to MS-DOS 16-bit programs. I don't know what delay() is. What compiler are you using?

I am using visual c 6 compiler. The sleep function works but the problem with the clock_t type remains. As I told you clock_t is a type, which is used by the function clock() to return time in milliseconds or CLOCKS_PER_SEC. I need to display them, but I cannot use the normal display functions. The only way I can display this type is by converting it co char type, or indirectly by converting it to integer and latter converting to char.

If all you want to do is display the value of it, one way to convert it to char * is to use sprintf() function:

Code:

---

char buffer[126];
clock_t time = clock();
sprintf(buffer,"%d", time);
cout << buffer;
