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 a 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 a 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:
