boost/cstdint.hpp Header
boost/cstdint.hpp The header <boost/cstdint.hpp>
-places the contents of the header <boost/stdint.h>
-in namespace boost. That header consists entirely of typedef's useful for
-writing portable code that requires certain integer widths.
The specifications are based on the ISO/IEC 9899:1999 C Language standard
-header stdint.h. The 64-bit types required by the C standard are not
+header <stdint.h>. The 64-bit types required by the C standard are not
required in the boost header, and may not be supplied in all implementations,
because long long is not [yet] included in the C++ standard.
See cstdint_test.cpp for a test program.
