std::operator<<(std::basic_stacktrace)
Defined in header <stacktrace> |
||
|---|---|---|
|
(since C++23) |
Inserts the description of st into the output stream os. Equivalent to return os << std::to_string(st);.
Parameters
| os | - | an output stream |
| st | - | a basic_stacktrace whose description is to be inserted |
Return value
os.
Exceptions
May throw implementation-defined exceptions.
Example
#include <stacktrace>
#include <iostream>
int main()
{
std::cout << "The stacktrace obtained in the main function:\n";
std::cout << std::stacktrace::current() << '\n';
[]{
std::cout << "The stacktrace obtained in a nested lambda:\n";
std::cout << std::stacktrace::current() << '\n';
}();
}Possible output:
The stacktrace obtained in the main function:
0# 0x0000000000402E7B in ./prog.exe
1# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
2# 0x0000000000402CD9 in ./prog.exe
The stacktrace obtained in a nested lambda:
0# 0x0000000000402DDA in ./prog.exe
1# 0x0000000000402EB2 in ./prog.exe
2# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
3# 0x0000000000402CD9 in ./prog.exeSee also
