NAME¶

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

Synopsis¶

std::uintmax_t hard_link_count() const; (1) (since C++17)
std::uintmax_t hard_link_count( std::error_code& ec ) const (2) (since C++17)
noexcept;

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.
