= `BOOST_ARCH_WORD_BITS`
|

|
|
|
||
|
|
Detects the native word size, in bits, for the current architecture. There are
|
||
|
|
two types of macros for this detection:
|
||
|
|
|
||
|
|
* `BOOST_ARCH_WORD_BITS`, gives the number of word size bits
|
||
|
|
(16, 32, 64).
|
||
|
|
* `BOOST_ARCH_WORD_BITS_16`, `BOOST_ARCH_WORD_BITS_32`, and
|
||
|
|
`BOOST_ARCH_WORD_BITS_64`, indicate when the given word size is
|
||
|
|
detected.
|
||
|
|
|
||
|
|
They allow for both single checks and direct use of the size in code.
|
||
|
|
|
||
|
|
NOTE: The word size is determined manually on each architecture. Hence use of
|
||
|
|
the `wordsize.h` header will also include all the architecture headers.
