std::to_string(3) C++ Standard Libary std::to_string(3) NAME std::to_string - std::to_string Synopsis Defined in header <stacktrace> std::string to_string( const std::stacktrace_entry& f ); (since C++23) Returns a string with a description of f. The standard recommends that the description should provide informa- tion about the contained evaluation, including information from f.source_file() and f.source_line(). Parameters f - a stacktrace_entry whose description is to be returned Return value A string with a description of f. Exceptions May throw implementation-defined exceptions. Notes Custom allocators support for this function is not provided, because the implementations usually require platform specific allocations, sys- tem calls and a lot of CPU intensive work, while a custom allocator does not provide benefits for this function as the platform specific operations take an order of magnitude more time than the allocation. Example // Run this code #include <stacktrace> #include <string> #include <iostream> int main() { auto st = std::stacktrace::current(); std::cout << "Description of an empty stacktrace entry:\n" + std::to_string(std::stacktrace_entry{}) << '\n'; if (st.size() > 0) { std::cout << "Description of a non-empty stacktrace entry:\n" + std::to_string(st[0]) << '\n'; } } Possible output: Description of an empty stacktrace entry: Description of a non-empty stacktrace entry: 0x0000000000402DE9 in ./prog.exe See also to_string returns a string with a description of the basic_stack- trace (C++23) (function template) http://cppreference.com 2024.06.10 std::to_string(3)
