void
Psetsysexit
(struct ps_prochandle
*P, const sysset_t *set);
The
Psetsysentry
()
and
Psetsysexit
()
set the system call entry and exit tracing flags respectively in the process
handle P to set. The call to
Psetsysentry
() or
Psetsysexit
() replaces the corresponding set of
system call tracing flags entirely with the new set. The system call entry
tracing flags cause a thread to stop on entry to the system call and the
exit tracing flags cause a thread to stop on return from the system call,
before control returns back to the user land process. For more information
on the state of the thread and for information on manipulating the
sysset_t,
see proc(5).
Note that only active processes may have their system call tracing flags updated. Process handles that refer to core files, zombie processes, and files do not have fault tracing flags and this function is a no-op on them.
See LOCKING in libproc(3LIB).
