\param f function be called for each match
- \retval 0 Operation complete.
+ \retval 0 Operation complete. Function f returned zero value always
\retval >0 Operation incomplete. Function f returned a non-zero value
\retval -1 error (such as bad regular expression)
\param after number of terms to be visited following str
\param client client data pointer to be passed to match function f
