Returns a string with a description of st.
The description of a basic_stacktrace typically contains description of its entries, although the number of lines is not required to be equal to size().

[edit] Parameters
| st | - | a basic_stacktrace whose description is to be returned
|
[edit] Return value
A string with a description of st.
[edit] Exceptions
May throw implementation-defined exceptions.
[edit] Notes
Custom allocators support for this function is not provided, because the implementations usually require platform specific allocations, system 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.
[edit] Example
Run this code
#include <stacktrace> #include <string> #include <iostream> int main() { auto trace = std::stacktrace::current(); std::cout << std::to_string(trace) << '\n'; }
Possible output:
0# 0x0000000000402D97 in ./prog.exe 1# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6 2# 0x0000000000402CA9 in ./prog.exe
