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).
[edit] Parameters
ec
-
out-parameter for error reporting in the non-throwing overload
[edit] Return value
The number of hard links for the referred-to filesystem object.
[edit] 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.
