The Linux kernel support files for gnumach make use of a few header files from the Linux Kernel sources. Among these are asm/unistd.h and asm/ptrace.h These files include various #define's, including things like __NR_fork 2, which are used to associate names with various linux system call numbers.
How do we implement this same strategy under the Hurd? Is a 'fork' system call made on the Hurd still associated with system call number 2? I don't see any file with similar definitions in it. Furthermore, the asm/ptrace.h file under Linux defines a structure for the way information is stored on the stack during a system call. Is this precisely the same for the Hurd? Or is there a separate mapping listed in the gnumach or hurd sources someplace? Thanks, -Brent
