SYNOPSIS

syscall(number, arg, ...)

DESCRIPTION

Syscall performs the system call whose assembly language interface has the specified number, and arguments arg .... 

The register d0 value of the system call is returned.

When the C-bit is set, syscall returns −1 and sets the external variable errno (see intro(2)).

BUGS

There is no way to simulate system calls such as pipe(2), which return values in register d1.
