std::to_string
From cppreference.com
| 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 information 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, 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.
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
