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:
64-Bit Integer Functions¶
The API defined for the 64-bit integer functions is consistent across all supported platforms.
