__GNU_CXX::__MT_ALLOC(3cxx)

💅 __gnu_cxx::__mt_alloc< _Tp, _Poolp > — the 3cxx manual page, bestie 💅

💖 NAME 💖

__gnu_cxx::__mt_alloc< _Tp, _Poolp > — okay so this is a fixed size (power of 2) allocator which - when compiled with thread support - will maintain one freelist per size per thread plus a global one. Steps are taken to limit the per thread freelist sizes (by returning excess back to the global list).

✨ SYNOPSIS ✨

#include <mt_allocator.h>

Inherits __gnu_cxx::__mt_alloc_base< _Tp >.

💫 Detailed Description 💫

Template time, bestie — here’s the exact declaration, quote mark and all:

template<typename _Tp, typename _Poolp = __common_pool_policy<__pool,  true >>
class __gnu_cxx::__mt_alloc< _Tp, _Poolp >"This is a fixed size (power of 2) allocator which - when compiled with thread support - will maintain one freelist per size per thread plus a global one. Steps are taken to limit the per thread freelist sizes (by returning excess back to the global list).

And yes, that " after > is literally chillin’ in the supplied declaration line — not fixing it, because facts stay facts. 🫶

Okay that’s the whole page, bestie. Big sparkle sign-off from the libstdc++ source/version crew and the 3cxx manual-page footer — the footer’s date spot isn’t separately visible in the supplied footer, so no invented dates, periodt. 🫶✨🎀
