std::experimental::filesystem::copy_symlink(3)

NAME
std::experimental::filesystem::copy_symlink - std::experimental::filesystem::copy_symlink

Synopsis
   Defined in header <experimental/filesystem>
   void copy_symlink( const path& from, const path& to ); (1) (filesystem TS)
   void copy_symlink( const path& from, const path& to, (2) (filesystem TS)
                      error_code& ec );
   Copies a symlink to another location.
   1) Effectively calls f(read_symlink(from), to) where f is create_symlink() or
   create_directory_symlink depending on whether from resolves to a file or directory.
   2) Effectively calls f(read_symlink(from, ec), to, ec) where f is create_symlink()
   or create_directory_symlink depending on whether from resolves to a file or
   directory.

Parameters
   from - path to a symbolic link to copy
   to - destination path of the new symlink
   ec - out-parameter for error reporting in the non-throwing overload

Return value
   (none)

Exceptions
   The overload that does not take an error_code& parameter throws filesystem_error on
   underlying OS API errors, constructed with from as the first argument, to as the
   second argument, and the OS error code as the error code argument. std::bad_alloc
   may be thrown if memory allocation fails. The overload taking an 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. This overload has
   noexcept specification:
   noexcept
