The top level keys are known as root keys and each key can 32 * contain subkeys and values. As with directories and sub-directories, 33 * the terms key and subkey are used interchangeably. Values, analogous 34 * to files, contain data. 35 * 36 * A specific subkey can be identifies by its fully qualified name (FQN), 37 * which is analogous to a file system path. In the registry, the key 38 * separator is the '\' character, which is reserved and cannot appear 39 * in key or value names. Registry names are case-insensitive. 40 * 41 * For example: HKEY_LOCAL_MACHINE\System\CurrentControlSet 42 * 43 * The HKEY_LOCAL_MACHINE root key contains a subkey called System, and 44 * System contains a subkey called CurrentControlSet. 45 * 46 * The WINREG RPC interface returns Win32 error codes. 47 */ 48 49#include <sys/utsname.h> 50#include <strings.h> 51 52#include <smbsrv/libsmb.h> 53#include <smbsrv/nmpipes.h> 54#include <smbsrv/libmlsvc.h> 55#include <smbsrv/ndl/winreg.ndl> 56 57/* 58 * List of supported registry keys (case-insensitive). 59 */ 60static char *winreg_keys[] = { 61 "HKLM", 62 "HKU", 63 "HKLM\\SOFTWARE", 64 "HKLM\\SYSTEM", 65 "System", 66 "CurrentControlSet", 67 "SunOS", 68 "Solaris", 69 "System\\CurrentControlSet\\Services\\Eventlog", 70 "System\\CurrentControlSet\\Control\\ProductOptions", 71 "SOFTWARE", 72 "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion" 73};
