Import registry file to registry using windows API

I am trying to write some C/C++ code that will import a .reg file into the registry. The MSDN has functions for importing a file for specific keys but I want to import for example the entire HKCU hive.

There is no Win32 API for importing a .reg file into the Registry 1. You will have to parse the file yourself and translate the instructions into appropriate Registry API function calls as needed - Reg(Open|Create)KeyEx(), RegSetValueEx(), RegDelete(Key|Value)(), etc.

1: don't be confused by the existence of RegLoadKey(), RegReplaceKey(), and RegRestoreKey(). They are intended for loading files created by RegSaveKey/Ex(), which are not text-based .reg files.

Otherwise, you can just use ShellExecute/Ex() or CreateProcess() to execute regedit.exe /s <filename> or reg.exe import <filename> with the path to the .reg file as a command-line parameter, letting regedit/reg handle the import for you. This would be the easiest way to go.
