17 * The sysmsg holds the kernelland version of a system call.
18 * It typically preceeds the usrmsg and syscall arguments in sysunion
19 * (see sys/sysunion.h)
34 * The usrmsg holds the userland version of the system call message which
35 * typically preceeds the original user arguments. This message structure
36 * is typically loaded by the copyin() and adjusted prior to copyout(), but
37 * not used in the nominal running of the system call.
