unsigned long long 과 uint64_t 가 다른가요?

#include <stdio.h>
#include <stdint.h>
 
extern uint64_t integer;
 
int main(){
    printf("%llu\n", integer);
}

<source>: In function 'main':
<source>:7:16: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 2 has type 'uint64_t' {aka 'long unsigned int'} [-Wformat=]
