size_type max_size() const noexcept; | (since C++23) |
Returns the maximum number of elements the underlying container (typically a std::vector
) is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end())
for the largest underlying container.
(none).
Maximum number of elements.
Constant.
This value typically reflects the theoretical limit on the size of the underlying container, at most std::numeric_limits<difference_type>::max()
. At runtime, the size of the container may be limited to a value smaller than max_size()
by the amount of RAM available.
#include <iostream> #include <stacktrace> int main() { std::stacktrace trace; std::cout << "Maximum size of a 'basic_stacktrace' is " << trace.max_size() << "\n"; }
Possible output:
Maximum size of a 'basic_stacktrace' is 1152921504606846975
(C++23) | returns the number of stacktrace entries (public member function) |
