std::experi...copy_symlink(3) C++ Standard Libarystd::experi...copy_symlink(3) NAME std::experimental::filesystem::copy_symlink - std::experimen- tal::filesystem::copy_symlink Synopsis Defined in header <experimental/filesystem> void copy_symlink( const path& from, const path& to); (1) (filesys- tem TS) void copy_symlink( const path& from, const path& to, (2) (filesys- tem TS) error_code& ec ); Copies a symlink to another location. 1) Effectively calls f(read_symlink(from), to) where f is cre- ate_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 over- load 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 argu- ment, 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 er- ror_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 See also copy copies files or directories (function) copy_file copies file contents (function) create_symlink creates a symbolic link create_directory_symlink (function) read_symlink obtains the target of a symbolic link (function) http://cppreference.com 2022.07.31 std::experi...copy_symlink(3)
