🫶 std::basic_stacktrace::current(3) — straight from the C++ Standard Libary 🫶

okay bestie, welcome to the std::basic_stacktrace::current(3) page from the C++ Standard Libary manual. this one is lowkey niche but highkey useful: it's all about grabbing a stacktrace of the current evaluation in the current thread. let's get into it ✨

✨ NAME ✨

std::basic_stacktrace::current — std::basic_stacktrace::current

(yes, that's the whole name section, and honestly? iconic repetition 💅)

🌈 Synopsis 🌈

here's the synopsis, copied exactly because we do not mess with signatures in this house 🫶

          static basic_stacktrace current( const allocator_type& alloc =
       (1) (since C++23)
                                               allocator_type() ) noexcept;
          static basic_stacktrace current( size_type skip, const
          allocator_type& alloc =
       (2) (since C++23)
                                               allocator_type() ) noexcept;
          static basic_stacktrace current( size_type skip, size_type
          max_depth,
                                                                             (3)
       (since C++23)
                                           const allocator_type& alloc =

                                               allocator_type() ) noexcept;

Let s[i] (0 ≤ i < n) denote the (i+1)-th stacktrace entry in the stacktrace of the current evaluation in the current thread of execution, where n is the count of the stacktrace entries in the stackentry.

1. (1) — Attempts to create a basic_stacktrace consisting of s[0], s[1], ..., s[n - 1].
2. (2) — Attempts to create a basic_stacktrace consisting of s[m], s[m + 1], ..., s[n - 1], where m is min(skip, n).
3. (3) — Attempts to create a basic_stacktrace consisting of s[m], s[m + 1], ..., s[o - 1], where m is min(skip, n) and o is min(skip + max_depth, n). The behavior is undefined if skip + max_depth < skip (i.e. the mathematical result of skip + max_depth overflows). 🫠

In all cases, alloc is stored into the created basic_stacktrace and used to allocate the storage for stacktrace entries.

---

🎀 Parameters 🎀

• alloc — allocator to use for all memory allocations of the constructed basic_stacktrace
• skip — the number of stacktrace entries to skip
• max_depth — the maximum depth of the stacktrace entries

---

💖 Return value 💖

If the allocation succeeds, the basic_stacktrace described above.

Otherwise, an empty basic_stacktrace.
