This is according to printf(3) on my Linux system (the man page specifically says that j is used to indicate a conversion to an intmaxt or uintmaxt; in my stdint. h, both int64t and intmaxt are typedef'd in exactly the same way, and similarly for uint64t). I'm not sure if this is perfectly portable to other systems. The latest version of this topic can be found at Format Specification Syntax: printf and wprintf Functions.

So you can use format specifier ll From the C Standard Then you can use format specifier" " PRIu64 to print your value: i. e. printf(" " PRIu64" \n"ram); You can refer this question also How to print a int64t type in C Oct 08, 2008 Hi guys.

Can anyone explain me how i can printf variables of the type uint64t? Thank you. printf format string refers to a control parameter used by a class of functions in the inputoutput libraries of C and many other programming languages. n is the number of the parameter to display using this format specifier, allowing the parameters provided to be output multiple times, using varying format specifiers or in different orders
