Возвращаемое значение (Return value)
On success, seccomp() returns 0. On error, if
SECCOMP_FILTER_FLAG_TSYNC was used, the return value is the ID of
the thread that caused the synchronization failure. (This ID is
a kernel thread ID of the type returned by clone(2) and
gettid(2).) On other errors, -1 is returned, and errno is set to
indicate the error.
