+Long Long integers
+==================
+
+This chapter describes the global functions you use to perform 64-bit
+integer operations. 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
+~~~~~~~~~~~~~~~~~~~~
+
+NSPR provides two types to represent 64-bit integers:
+
+-  :ref:`PRInt64`
+-  :ref:`PRUint64`

+The API defined for the 64-bit integer functions is consistent across
+all supported platforms.
