const_reference at( size_type pos ) const;		(since C++23)

Returns a reference to the entry at specified location pos, with bounds checking.

If pos is not within the range of the stacktrace, an exception of type std::out_of_range is thrown.

Parameters

pos

-

position of the stacktrace entry to return

Return value

Reference to the requested entry.

Exceptions

std::out_of_range if pos >= size().

Complexity

Constant.
