getsid

Implemented in Antinomie 0.7.0 · Syscall list

long getsid(pid_t pid);
Number (x86-64) 124
ABI common
Kernel entry point sys_getsid

This is the raw kernel prototype from the pinned Linux 6.12.94 schema, not the libc wrapper.

Returns the session id of a given process.

Name Type Meaning
pid (arg0) pid_t Process or thread id.

On success: the session id.

In an Antinomie trace the Return column and the ret filter field show the raw kernel return value. On failure that is the negative errno, for example -2 for ENOENT, not the -1 plus errno that the libc wrapper gives. syscall.errno holds the positive errno and syscall.success is false.

Raw return Name Meaning
-3 ESRCH No such process or thread.

getsid(2) on man7.org

Coverage mark: Implemented. All arguments are plain values, recorded as the raw argument words at entry. There is no pointee to copy and no known gap.

Every call is recorded as an Entry record (the six argument words and the pointees copied at entry) and an Exit record (the return value and the pointees copied at exit).

Argument When How Recorded field key Condition
pid (arg0) Entry raw scalar word args.0, args.pid
  • Result: ret, syscall.errno, syscall.success, syscall.duration_ns.
  • Argument words: args.pid (arg0); args.0 to args.5 by position.

See Syscall Trace filter for the full syntax.
