std::filesystem::directory_entry::hard_link_count: std::filesystem::directory_entry::hard_link_count

NAME

std::filesystem::directory_entry::hard_link_count - std::filesystem::directory_entry::hard_link_count

Synopsis

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

If the number of hard links is cached in this directory_entry, returns the cached value. Otherwise, returns std::filesystem::hard_link_count(path()) or std::filesystem::hard_link_count(path(), ec), respectively

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

The overload that does not take a std::error_code& parameter throws 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. The overload taking a std::error_code& parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear() if no errors occur. Any overload not marked noexcept may throw std::bad_alloc if memory allocation fails.
