From cppreference.com
std::uintmax_t hard_link_count() const;

(1) | (since C++17) |
std::uintmax_t hard_link_count( std::error_code& ec ) const noexcept;

(2) | (since C++17) |
If the number of hard links is cached in this directory_entry, returns the cached value. Otherwise, returns:
1)
std::filesystem::hard_link_count(path()),2)
std::filesystem::hard_link_count(path(), ec).Parameters
| ec | - | out-parameter for error reporting in the non-throwing overload |
Return value
The number of hard links for the referred-to filesystem object.
Exceptions
Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
1) Throws std::filesystem::filesystem_error on underlying OS API errors, constructed with
p as the first path argument and the OS error code as the error code argument.2) Sets a
std::error_code& parameter to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur.Example
