.SH DESCRIPTION
.sp
.LP
The \fBsof_bypass()\fR function informs the framework that the filter instance no longer wants to receive callbacks. No guarantee is made that there will not be any active callbacks when \fBsof_bypass()\fR returns, only that no new callbacks will be triggered.
.sp
.LP
The only callback that will triggered for a filter that has called \fBsof_bypass()\fR is \fBsofop_detach\fR(9E).
.sp
.LP
A typical use of \fBsof_bypass()\fR is for a filter that only needs to be active during a certain period of a socket's lifetime. Calling \fBsof_bypass()\fR will minimize the performance impact of the inactive filter.
