* .Pp
* ANSI C89 (or C99 for that matter) provides no required mechanism
* for 64 bit integers. Nevertheless, many compilers provide them as
* extensions. However, since it is not a gaurantee, and to be fully
* standards-compliant and thus portable, a platform-agnostic interface
* is required. This header provides such an interface. If the platform
* has a 64 bit integer type, that is used, and native operations are
* performed by C preprocessor macro expansion. Otherwise, a
* compatibility layer is provided, which implements 64-bit
* arithmetic on an array of 2 32-bit numbers which are provided by
* .Xr Int 3 .
* .Pp
* Note that 64-bit emulation is certainly not as performant as using
* native 64-bit operations, so whenever possible, the native
* operations should be preferred. However, since C provides no required
* 64 bit integer on 32-bit and less platforms, this API can be used as
* a "good enough" fallback mechanism.
* .Pp
* Also note that this implementation, both in the native and
* non-native forms, makes some assumptions:
* .Bl -bullet -width Ds
* .It
* When a cast from a larger integer to a smaller integer is performed,
* the upper bits are truncated, not the lower bits.
* .It
* Negative numbers are represented in memory and in registers in two's
* compliment form.
* .El
* .Pp
* This API may provide unexpected output if these assumptions are
* false for a given platform.

* .Pp
* ANSI C89 (or C99 for that matter) provides no required mechanism
* for 64 bit integers. Nevertheless, many compilers provide them as
* extensions. However, since it is not a gaurantee, and to be fully
* standards-compliant and thus portable, a platform-agnostic interface
* is required. This header provides such an interface. If the platform
* has a 64 bit integer type, that is used, and native operations are
* performed by C preprocessor macro expansion. Otherwise, a
* compatibility layer is provided, which implements 64-bit
* arithmetic on an array of 2 32-bit numbers which are provided by
* .Xr Int 3 .
* .Pp
* Note that 64-bit emulation is certainly not as performant as using
* native 64-bit operations, so whenever possible, the native
* operations should be preferred. However, since C provides no required
* 64 bit integer on 32-bit and less platforms, this API can be used as
* a "good enough" fallback mechanism.
* .Pp
* Also note that this implementation, both in the native and
* non-native forms, makes some assumptions:
* .Bl -bullet -width Ds
* .It
* When a cast from a larger integer to a smaller integer is performed,
* the upper bits are truncated, not the lower bits.
* .It
* Negative numbers are represented in memory and in registers in two's
* compliment form.
* .El
* .Pp
* This API may provide unexpected output if these assumptions are
* false for a given platform.
