0 // 8 is the actual number of in register arguments //++ // // Module Name: // // systable.s // // Abstract: // // This module implements the system service dispatch table. // // Author: // // William K. Cheung (wcheung) 5-Mar-1996 // // Environment: // // Kernel mode only. // // Revision History: // //--
// // To add a system service simply add the name of the service to the below // table. If the system service has in memory arguments, then immediately // follow the name of the service with a comma and following that the number // of bytes of in memory arguments, e.g. CreateObject,40. // // N.B. Note that the gp corresponding to KiServiceTable must be placed // just before KiServiceTable. // Given that code must be at least 16-byte aligned, bits 1-3 are used // used to encode number of arguments up to a value of 7. The following // forumal is used numargs > 8 ? (((numargs - 8 + 1)/2) + 8) : numargs //
