This command resolves both system call names and numbers with respect to the given architecture supplied in the optional ARCH argument. If the architecture is not supplied on the command line then the native architecture is used. If the "-t" argument is specified along with a system call name, then the system call will be translated as necessary for the given architecture. The "-t" argument has no effect if a system call number is specified.
In some combinations of architecture and system call, a negative system call number will be displayed. A negative system call number indicates that the system call is not defined for the given architecture and is treated in a special manner by libseccomp depending on the operation.
