TJwInternalJobObjectIOCompletitionThread is for internal use only. | |
|
|
TJwJobObject is the main job class. It encapsulates a job object and provides methods and properties to maintain it. There are also events that are fired on special job messages. All processes of a session must have the same token session id, otherwise the assignment fails. | |
|
|
TJwJobObjectSessionList manages a list of job objects threadsafe. Since every process in a job must be in the same session, the list manages one job object per session. This solution is only available in Windows Vista and later. | |
|
|
TJwLibraryUtilities contains methods related to libraries. |

JwCreateProcessAsAdminUser logs on a user and creates a new process under its logon session. The user will be a member of administrators group for this process but not in the user database. In Vista the linked token will be retrieved which has the administrator group enabled. The user does not have to be an administrator at all! | |
|
|
JwCreateProcessInSession creates a new process in a user's session using various ways to achieve success. This procedure needs JwInitWellKnownSIDs to be called. To run a process in another session the process needs SYSTEM rights. It means that the current process token must have the TOKEN_ASSIGN_PRIMARY right for the target token. Otherwise the CreateProcessAsUser function fails with bad error explanation (like "A call to an OS function failed"). However the procedure won't stop you from doing this! | |
|
|
GetProcessSessionID returns the session ID of a process given by handle or ID. | |
|
|
JwGetTokenFromProcess tries to retrieve a token from a process. For this purpose it enumerates all processes on the local machine (even from other users) and calls the callback method OnProcessFound to determine whether the given process should be used to return the token. | |
|
|
JwProcessIdToSessionId returns the session ID of a process. This function uses the new API of Vista or otherwise calls just JwGetProcessSessionID. It ist faster because it does not create an object if run on Vista or newer. |

This is record TInternalProcessData. | |
|
|
TJwCreateProcessInfo contains extra information for JwCreateProcessAsAdminUser | |
|
|
TJwCreateProcessOut contains output information after the process has started. Some of these information must be freed manually. | |
|
|
TJwCreateProcessParameters contains information supplied to CreateProcessAsUser | |
|
|
TJwProcessOutputInformation contains information about result from JwCreateProcessInSession. |

This is type PInternalProcessData. | |
|
TJwOnJobNotification is called when a job notification occurs. | |
|
TJwOnNewJobObject is called by TJwJobObjectSessionList.AssignProcessToJob for every new job object that mus be created. The callback event must create a new job object and return it through parameter NewJobObject. The return value must not be nil. The new job object does not need to have a name. | |
|
TJwOnNoActiveProcesses will be called when the job object ran out of processes. | |
|
IJwJobObject = interface [IID_IJwJobObject] procedure AssignProcessToJobObject(hProcess : TJwProcessHandle); BOOL WINAPI AssignProcessToJobObject(HANDLE hJob, HANDLE hProcess); HANDLE WINAPI CreateJobObject(LPSECURITY_ATTRIBUTES lpJobAttributes,LPCTSTR lpName); HANDLE WINAPI OpenJobObject(DWORD dwDesiredAccess,BOOL bInheritHandles, LPCTSTR lpName); BOOL WINAPI SetInformationJobObject(HANDLE hJob,JOBOBJECTINFOCLASS JobObjectInfoClass, LPVOID lpJobObjectInfo,DWORD cbJobObjectInfoLength); BOOL WINAPI QueryInformationJobObject(HANDLE hJob, JOBOBJECTINFOCLASS JobObjectInfoClass, LPVOID lpJobObjectInfo, DWORD cbJobObjectInfoLength, LPDWORD lpReturnLength); BOOL WINAPI IsProcessInJob(HANDLE ProcessHandle, HANDLE JobHandle, PBOOL Result); BOOL WINAPI TerminateJobObject(HANDLE hJob, UINT uExitCode); end; |
