C Programming – Format Specifier for ‘long long’

c++

I declare a variable for a 64 bit counter as :

long long call_count;

What is the format specifier that I should use in print statements?

I tried, %l, %ld, %ll. None seems to be correct.

I use Diab C compiler for compiling my application code to run on pSOS operating system.

According to C99, it should be "%lld" (see, for example,here). If Diab C isn't C99, then you'd have to look at the compiler docs, which I can't seem to find online with a quick Googling.
