int
pr_getitimer(struct ps_prochandle *P, int which, struct itimerval *itv);

The () function injects the getitimer(2) system call into the target process P by means of the agent LWP. If the process handle P is NULL then this will be equivalent to calling getitimer(2) on the currently running process.

The arguments which and itv have the same meaning as in getitimer(2). See getitimer(2) for the full description and purpose of the system call and its arguments.

The () function only works on active processes. Process handles that correspond to core files, zombie processes, or ELF objects do not support system call injection.

Upon successful completion, the pr_getitimer() function's return value is that described in getitimer(2). Otherwise, is returned and is set to ENOSYS to indicate that the system call could not be injected.

For the full list of errors see the ERRORS section in getitimer(2).

The pr_getitimer() function will fail if:

An error occurred while trying to invoke the agent LWP and inject a system call in the process handle P or the process handle P does not support system call injection.

See in libproc(3LIB).
