Macro Definition Documentation

ALIB_SIZEOF_INTEGER

#define ALIB_SIZEOF_INTEGER

Contains the size of std::size_t, std::ptrdiff_t, void*, alib::integer, and alib::uinteger, which all should be the same, but independent on the compiler and platform (processor type). Usually, this configuration macro is deduced (in the internal header lang/integers.inl). If this deduction fails, this may result in two possible outcomes:

1. A dedicated compilation error hinting to this documentation.
2. Less directly connected compilation errors.

In this case, the right value has to be provided to the compiler. When doing this, configuration macros

• ALIB_INTGAP_TYPE,
• ALIB_SIZEOF_INTGAP,
• ALIB_SIZEOF_LONGDOUBLE_REPORTED, and
• ALIB_SIZEOF_LONGDOUBLE_WRITTEN

have to be provided as well. This is true for each of these configuration macros: If one of them is given explicitly to the compiler, all the five have to be given. Otherwise, an explicit error message will be given during compilation.
