66 * This is confusingly named. It holds per-thread state about the
67 * currently executing system call. syscall.h defines a struct
68 * syscall that holds metadata used to format system call arguments.
70 * NB: args[] stores the raw argument values (e.g. from registers)
71 * passed to the system call. s_args[] stores a string representation
72 * of a system call's arguments. These do not necessarily map one to
73 * one. A system call description may omit individual arguments
74 * (padding) or combine adjacent arguments (e.g. when passing an off_t
75 * argument on a 32-bit system). The nargs member contains the count
76 * of valid pointers in s_args[], not args[].
