/* CopyIniPrinterSecurityDescriptor
|
|
*
|
|
* Copies the security descriptor for the printer to the buffer provided
|
|
* on a call to GetPrinter. The portions of the security descriptor which

|
* will be copied are determined by the accesses granted when the printer
|
|
* was opened. If it was opened with both READ_CONTROL and ACCESS_SYSTEM_SECURITY,
|
|
* all of the security descriptor will be made available. Otherwise a
|
|
* partial descriptor is built containing those portions to which the caller
|
|
* has access.
|
|
*
|
|
* Parameters
|
|
*
|
|
* pIniPrinter - Spooler's private structure for this printer.
|
|
*
|
|
* Level - Should be 2 or 3. Any other will cause AV.
|
|
*
|
|
* pPrinterInfo - Pointer to the buffer to receive the PRINTER_INFO_*
|
|
* structure. The pSecurityDescriptor field will be filled in with
|
|
* a pointer to the security descriptor.
|
|
*
|
|
* pEnd - Current position in the buffer to receive the data.
|
|
* This will be decremented to point to the next free bit of the
|
|
* buffer and will be returned.
|
|
*
|
|
* GrantedAccess - An access mask used to determine how much of the
|
|
* security descriptor the caller has access to.
|
|
*
|
|
* Returns
|
|
*
|
|
* Updated position in the buffer.
|

*
|
|
* NULL if an error occurred copying the security descriptor.

|
* It is assumed that no other errors are possible.

|
|
*
|
|
* pIniPrinter - A pointer to the spooler's internal data structure
|
|
* for the printer concerned.
|
|
*
|
|
* Level - Level of information requested (1, 2 or 3). Any level

|

*
|
|
* pPrinterInfo - Pointer to the buffer to receive the PRINTER_INFO_*
|

* structure.
|

*

* pEnd - Current position in the buffer to receive the data.
|
|
* This will be decremented to point to the next free bit of the

* buffer and will be returned.
|
|
*
|
|
* pSecondPrinter - If the printer has a port which is being controlled
|
|
* by a monitor, this parameter points to information retrieved
|
|
* about a network printer. This allows us, e.g., to return
|
|
* the number of jobs on the printer that the output of the
|
|
* printer is currently being directed to.
|
|
*
|
|
* Remote - Indicates whether the caller is remote. If so we have to
|
|
* include the machine name in the printer name returned.
|
|
*
|
|
* CopySecurityDescriptor - Indicates whether the security descriptor
|
|
* should be copied. The security descriptor should not be copied
|
|
* on EnumPrinters calls, because this API requires
|
|
* SERVER_ACCESS_ENUMERATE access, and we'd have to do an access
|
|
* check on every printer enumerated to determine how much of the
|
|
* security descriptor could be copied. This would be costly,
|
|
* and the caller would probably not need the information anyway.
|
|
*
|
|
* GrantedAccess - An access mask used to determine how much of the
|
|
* security descriptor the caller has access to.
|
|
*
|
|
*
|
|
* Returns
|
|
*
|
|
* A pointer to the point in the buffer reached after the requested
|
|
* data has been copied.
|
|
*
|
|
* If there was an error, the return value is NULL.
|
|
*
|
|
*
|
|
* Assumes
|
|
*
|
|
* The largest PRINTER_INFO_* structure is PRINTER_INFO_2.

|
|
* 1: A multi-user system with 200 users each with their

|
|
* "Client" printers are owned by the user of that station,

* and by default only allow print access for that user.
|
|
* This provides a simple way of filtering printers to show
|
|
* to the user for a selection.
|
|
*
|
|
* 2: Programs such as Windows write get confused when

|
* they see a printer they can not open. This is a bad
|
|
* program, since normal NT can have a printer denied to a user, but we must
|
|
* make it work anyway.
