std::filesystem::directory_entry::assign

void assign( const std::filesystem::path& p );
void assign( const std::filesystem::path& p, std::error_code& ec );
(since C++17)

Assigns new content to the directory entry object. Sets the path to p and calls refresh to update the cached attributes. If an error occurs, the values of the cached attributes are unspecified.

Parameters

p - path to the filesystem object to which the directory entry will refer
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 p as the first 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.
