long long array

[25884]

I have an array of 'long long' type in C.
I want to return this back to java using JNI, what should be the return type of my JNI method for it to accept a long long type uni dim array?
I tried using jlongArray, but it gives me
" return value type does not match the function type

Well the Java long is :

8 bytes signed (two's complement). Ranges from -9,223,372,036,854,775,808 to +9,223,372,036,854,775,807.

I've no idea how many bytes a "long long" is, but I doubt it is the above. You need to match your C types to java types. For example, a C char = Java byte.

Types differ in c/c++ from implementation to implementation.
But I guess you're right for most common actual Cs.
