std::filesystem::directory_entry::replace_filename: std::filesystem::directory_entry::replace_filename


std::filesystem::directory_entry::replace_filename - std::filesystem::directory_entry::replace_filename


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

Changes the filename of the directory entry.
Effectively modifies the path member by path.replace_filename(p) and calls refresh to update the cached attributes. If an error occurs, the values of the cached attributes are unspecified.
This function does not commit any changes to the filesystem.


p - the path to append to the parent path of the currently stored path
ec - out-parameter for error reporting in the non-throwing overload

Return value



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.
