Whole numbers

The Java data type long is a 64-bit data type which is represented in the JNI by the C data types jlong

The C/C++ compiler (as of version 3.0B) supports the data type longlong or int64_t, which is compatible with the above mentioned data types (i.e. jlong). This means that this data can be used in C without any further precautionary measures being required. The scope of the support available through C runtime system functions as of CRTE V2.1B is explained in the appropriate CRTE documentation.
