How should I print types like off_t and size_t?

I'm using fstat(stream, &fs) to get a file size in C which returns type off_t.

Printing this just gives a warning:

format ‘%d’ expects type ‘int’, but argument has 开发者_JAVA技巧type ‘off_t’

Any ideas how to print this without compiler errors?

Offset types are usually long integers. Cast it, and print it accordingly.

The actual type below off_t is defined in sys/types.h. You can look it up!

Found the answer, use:

%lld

Works without any casting.
