Re: RPG IV equivalent to long long

I am looking to call the function

The first two parms should be ok as 10U 0 in RPG as will the last.
That just leaves the _C_mallinfo_t which is defined as
typedef struct _C_mallinfo_t {

unsigned long long int total_bytes;
+ 7 other fields that are unsigned long long int } _C_mallinfo_t;

I've never come across a long long before, is that a 20U 0, or
something even bigger?

I reckon if i have a pointer to the following it should do the
trick

D mallinfo DS
D field1 20u 0
D 7 others

But I thought I'd check here as someone would probably know
exactly what an unsigned long long maps to in RPG

The type "unsigned long long" is 64 bits for twenty digits per the following link; plus others described:
http://en.wikipedia.org/wiki/Integer_(computer_science)#Common_integral_data_types

The 20u00 declaration establishing the RPG 8-byte unsigned integer data type would be an equivalent to the unsigned long long type declaration.
