macOS delay() mac os x

[aiquecarago]

Hello

I started a few months ago learning how to program in C with xCode.

Now i have to make a program that uses functions like delay(), but can't figure out how to do it in mac os X.

for example:

main(){

printf("Hello");

delay(1000); //have to wait 1 second to print world

printf("World");
}

Any help?
Thanks in advance

Use the sleep() function from the standard C library. The prototype is:

#include <unistd.h>

unsigned int sleep(unsigned int seconds)


For more info, do a man on sleep. There are other variants like usleep, nanosleep, etc.

try sleep(1) instead.

Already tried it, but not working:

with sleep and other functions like sleep when i run the program he first wait 1 second and then print the two printf's, and i want the program to print the first printf, wait a second and then print the second printf. It's weird. Any help?

The output stream is buffered up to newlines. You either need to put a "\n" at the end of your strings or call this after (at least) the first printf:
fflush(stdout);

C is timeless, therefore so is this thread.
