Abstract
In a method for converting a system call for an origin operating system into a system call for a destination operating system, an emulation routine is called. The emulation routine converts a reference structure comprising a reference value and at least one referenced element by converting at least the reference value, and it performs the system call for the destination operating system This method makes it possible to run application programs on a destination system without specific adaptation or retranslation, and even when the original operating system has not been ported to the destination system.
Claims12
A method for converting a system call for an origin operating system into a system call for a destination operating system, comprising the steps of:
- providing at least one reference structure which comprises at least one reference value with aid of which at least one referenced element of the reference structure can be accessed;
- calling an emulation routine;
- with the emulation routine, converting said reference structure by converting at least said reference value;
- and
- with the emulation routine, performing the system call for the destination operating system, at least the reference value of the system call for the origin operating system being saved for use in further subsequent origin system calls to be converted for the destination operating system.
