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
(

.
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.
