View Full Version : hardlock emulation
| [Originally Posted by SysCall]Hi, do you really need to go kernel mode? Some years ago (almost forgot) i emulated the HL API at user mode level by implementing HL API providing my own hlvdd.dll. |
| [Originally Posted by SysCall] About kernel mode ... a good disassembly/analysis/deadlist of the kernel mode driver and its user mode equivalent (hlvdd.dll) + the HL API SDK should give some hints... |
| Have you emulated HLM_CHECKALLSLOTS in your's hlvdd.dll? |
)HLM_CHECKALLSLOTS(BUFLEN,BUFFER) Checks all slots (LiMaS only). Arguments BUFLEN After the function is performed, this variable returns the actual buffer length occupied. The function only returns the required buffer length if the value of the BUFLEN and BUFFER variables is 0. (32-bit) BUFFER Pointer to the HL_LIS data structure which contains the slot and license information. Refer to "The HL-LIS Data Structure" section for more information. Return The return value contains the API status. Use If you are using licensing, this function queries the current status of all slots. Example result = HLM_LOGIN(29809,DONT_CARE,"HARDLOCK","@0=/&#s3", RUS_VK, 0,"378p,IPX" ;IF (result == STATUS_OK) result = HLM_CHECKALLSLOTS(BUFLEN,BUFFER); . . result = HL_LOGOUT(); ENDIF; |
| HLM_CHECKEXPDATE(SLOT,YEAR,MONTH,DAY) Returns the expiration date (HL-RUS/LiMaS). Arguments SLOT Defines the slot number. Slot number 0 indicates the global expiration date for local modules and Hardlock Server modules. For Hardlock Server the expiration dates for the single slots (1- 32767) can also be checked. (32-bit) YEAR Pointer for the variable in which the expiration year is returned. (16-bit) MONTH Pointer for the variable in which the expiration month is returned. (16-bit) DAY Pointer for the variable in which the expiration day is returned (16-bit). Return The system returns the API status (see chapter 4.1). Use If you use the expiration date option, this function checks when the license expires. This can be done separately for each slot if you are using Hardlock Server. The global expiration date (local and server) is returned using slot 0. Example result = HLM_LOGIN(29809,DONT_CARE,"HARDLOCK","@0=/&#s3", RUS_VK, 0,"378p,IPX" ;IF (result == STATUS_OK) result = HLM_CHECKEXPDATE(0, &year, &month, &day); IF (result == RUS_DATE_EXPIRED) PRINT("Global expiration date exceeded" ;. . result = HL_LOGOUT(); ENDIF; |
The HL-LIS Data Structure The HL_LIS data structure contains the global license information. current_date 16-bit Current date (days since 01.01.1999). res 16-bit Reserved. num_slots 32-bit Number of slots. glob_exp_date 16-bit Global expiration date (days since 01.01.1999). res2 16-bit Reserved. slots[ ] Depending on number of slots Pointer to the first HL_SIS structure, see below. The HL_SIS data structure The HL_SIS contains license information for the individual slots. max_user 32-bit Maximum available licenses. cur_user 32-bit Number of licenses currently being used. exp_date 16-bit Expiration date for this slot. flag 8-bit 0 No singularity: Multiple calls of the slot on one computer take up the equivalent number of licenses. 1 Singularity: Multiple calls of the slot on one computer only take up one license. reserved 8-bit Reserved. |
