NAME

std::filesystem::copy_symlink - std::filesystem::copy_symlink

Synopsis

Defined in header <filesystem>
void copy_symlink( const std::filesystem::path& from, (1) (since C++17)
const std::filesystem::path& to);
void copy_symlink( const std::filesystem::path& from,

const std::filesystem::path& to, (2) (since C++17)

std::error_code& ec ) noexcept;

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::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.
