bd29e0dd15 Merge pull request #177 from ashtum/rename-base-typedef
Rename typedef `base` to `core_ev_base`
2024-07-13 13:21:00 +03:00
Mohammad Nejati
72761e34e0 Rename typedef base to core_ev_base
Using typedef `base` poses a high risk of name conflict, given that
`empty_value` is inherited in user types.

[section Revision History]
[section Changes in 1.86.0]
* Added a [link core.pointer_in_range `boost/core/pointer_in_range.hpp`] header with a `pointer_in_range`
function template to check if a pointer is within a given range.
* Fixed `type_name` for abstract classes. ([github_issue 172])
* Fixed `boost/core/type_name.hpp` compilation error with MSVC with disabled native `wchar_t` type.
([github_issue 173])
* Added a workaround for an MSVC [@https://developercommunity.visualstudio.com/t/Compiler-bug:-Incorrect-C2247-and-C2248/10690025 bug]
causing `empty_value` compilation errors when it is used with a nested class. ([github_pr 175])
[endsect]
[section Changes in 1.85.0]
* Added a new [link core.functor `boost/core/functor.hpp`] header with a `functor` class template
for wrapping a raw function into a function object class.
* Changed [link core.null_deleter `null_deleter`], [link core.fclose_deleter `fclose_deleter`]
and [link.checked_delete checked deleter] definitions so that they don't bring namespace `boost`
and [link core.checked_delete checked deleter] definitions so that they don't bring namespace `boost`
into argument-dependent lookup in cases like this:
```
std::unique_ptr< std::FILE, boost::fclose_deleter > p1, p2;
