how to get if_msghdr(net/if.h) info by system call

[agnewee]

I want to get the traffic information of the specified network card. After consulting the relevant files, I found that the if_msghdr structure has the information I want. But I can't find a  method or system call that can return information about this structure. Can someone help me?
