PURPOSE: To always make inquiries for decision of types of resources by offering a database of input/output resources to a device driver from a hardware resource manager. CONSTITUTION: The resources R-a 120, R-d 122 and R-f 124 have resource type Type-A 112, the resources R-b 126 and R-e 128 have resource Type-B 114, and a resource R-c 130 has resource Type-C 116 respectively. A 1st resource object Ctlr-A 132 includes the resource R-e 128, a 2nd resource object Ctlr-B 134 includes two resources R-a 120 and R-c 130, and the last resource object Ctlr-C 136 includes four resources R-b 126, R-c 130, R-d 122 and R-f 124. Thus, these resources can be used in common with each other and plural users can access the same resource. |
