- Consolidate duplicate code for printing the metadata at the start of each line into a shared function. - Add an -H option which will log the thread ID of the relevant thread for each event. While here, remove some extraneous calls to clock_gettime() in print_syscall() and print_syscall_ret(). The caller of print_syscall_ret() always updates the current thread's "after" time before it is called. Reviewed by: kib MFC after: 1 month Differential Revision: https://reviews.freebsd.org/D5363

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