INT 63 - DESQview/X - SOCKET API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. InstallCheck: test for the string "dvxunix" (yes, lowercase) at offset 9 from the interrupt handler start (see #03515) Notes: parameters are passed by patching (!) data field immediately following the entry point, as detailed below (see #03515); the preferred method for calling the socket API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running.
