Retrieves the environment variables for the specified user. This block can then be passed to the CreateProcessAsUser function.
BOOL CreateEnvironmentBlock( LPVOID *lpEnvironment, HANDLE hToken, BOOL bInherit );
When this function returns, receives a pointer to the new environment block. The environment block is an array of null-terminated Unicode strings. The list ends with two nulls (\0\0).
Token for the user, returned from the LogonUser function. If this is a primary token, the token must have TOKEN_QUERY and TOKEN_DUPLICATE access. If the token is an impersonation token, it must have TOKEN_QUERY access. For more information, see Access Rights for Access-Token Objects.
If this parameter is NULL, the returned environment block contains system variables only.
Specifies whether to inherit from the current process' environment. If this value is TRUE, the process inherits the current process' environment. If this value is FALSE, the process does not inherit the current process' environment.
TRUE if successful; otherwise, FALSE. To get extended error information, call GetLastError.
To free the buffer when you have finished with the environment block, call the DestroyEnvironmentBlock function.
If the environment block is passed to CreateProcessAsUser, you must also specify the CREATE_UNICODE_ENVIRONMENT flag. After CreateProcessAsUser has returned, the new process has a copy of the environment block, and DestroyEnvironmentBlock can be safely called.
User-specific environment variables such as %USERPROFILE% are set only when the user's profile is loaded. To load a user's profile, call the LoadUserProfile function.
