ifnet_stat_increment_in
Declaration
errno_t ifnet_stat_increment_in(ifnet_t interface, u_int32_t packets_in, u_int32_t bytes_in, u_int32_t errors_in);Parameters
- interface:
The interface.
- packets_in:
The number of additional packets received.
- bytes_in:
The number of additional bytes received.
- errors_in:
The number of additional receive errors.
Return Value
0 on success otherwise the errno error.
Discussion
This function is intended to be called by the driver. This function allows a driver to update the inbound interface counts. The most efficient time to update these counts is when calling ifnet_input.
A lock protects the counts, this makes the increment functions expensive. The increment function will update the lastchanged value.
