Please acquire a copy of the OpenVMS Internals and Data Structures manuals for OpenVMS VAX, and for OpenVMS Alpha, and examine the information included there on the internal processing involved in system service dispatching. In OpenVMS VAX, application programs resolve these symbols via the object module SYS$P1_VECTOR in SYS$SHARE:STARLET.OLB, and the system services are accessed via a fixed area of vectors located in "P1" process virtual address space (and in low "S0" space, for older programs). In OpenVMS Alpha, the LINKER processes SYS$PUBLIC_VECTORS.EXE and SYS$BASE_IMAGE.EXE, which is how the symbols associated with the operating system routines, such as system services, are resolved. | |||||
