The functions define a portable API that can be used +reliably in any environment. Where 64-bit integers are desired, use of +NSPR's implementation is recommended to ensure cross-platform +compatibility. + +Most of the 64-bit integer operations are implemented as macros. The +specific implementation of each macro depends on whether the compiler +for the target platform supports 64-bit integers. For a specific target +platform, if 64-bit integers are supported for that platform, define +``HAVE_LONG_LONG`` at compile time. + +.. _64-Bit_Integer_Types: + +64-Bit Integer Types +~~~~~~~~~~~~~~~~~~~~ + +NSPR provides two types to represent 64-bit integers: + +- :ref:`PRInt64` +- :ref:`PRUint64` + +.. _64-Bit_Integer_Functions: + +64-Bit Integer Functions +~~~~~~~~~~~~~~~~~~~~~~~~ + +The API defined for the 64-bit integer functions is consistent across +all supported platforms. |
