void copy_symlink( const path& from, const path& to, error_code& ec ); |
(2) | (filesystem TS) |
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.Contents |
[edit] 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 |
[edit] Return value
(none)
[edit] 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 hasnoexcept specification:
noexcept
