std::stacktrace_entry::source_file
Returns the presumed or actual name of the source file that lexically contains the expression or statement whose evaluation is represented by *this, or an empty string on failure other than allocation failure, e.g. when *this is empty.
# Declarations
std::string source_file() const;
(since C++23)
# Return value
The name of the source file specified above on success, an empty string on failure other than allocation failure.
# Notes
The presumed name of the source file is what the predefined macro FILE expands to, and can be changed by the #line directive.
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.
