| void copy_symlink( const std::filesystem::path& from, const std::filesystem::path& to, |
(2) | (since C++17) |
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 std::error_code& parameter throws filesystem_error on underlying OS API errors, constructed with from as the first path argument, to as the second 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.
