SYD-TSC(1) General Commands Manual SYD-TSC(1)

syd-tsc - Run a command without access to the timestamp counter

syd-tsc [-h] {command [args...]}

The syd-tsc(1) utility runs a command without access to the timestamp counter. Attempt to access the timestamp counter will cause the SIGSEGV signal to be delivered to the process.

-h Display help.

On clean exit, syd-tsc exits with the same code as the child process. On unclean termination, exit code is set to 128 plus signal number. In case denying the timestamp counter or executing the child process fails syd-tsc exits with the errno(3) number.
