6 .TH NET_GETMTU 9F "May 1, 2008"
8 net_getmtu \- determine the MTU of a given network interface
14 \fBint\fR \fBnet_getmtu\fR(\fBconst\fR \fBnet_data_t\fR \fInet\fR, \fBconst\fR \fBphy_if_t\fR \fIifp\fR);
20 Solaris DDI specific (Solaris DDI).
28 value returned from a successful call to \fBnet_protocol_lookup\fR(9F).
37 value returned from a successful call to \fBnet_phylookup\fR(9F) or
38 \fBnet_phygetnext\fR(9F).
44 The \fBnet_getmtu()\fR function receives information about the current
45 \fBMTU\fR of a network interface. The value returned from this function call
46 should not be cached as the \fBMTU\fR of a network interface since it is not
47 guaranteed to be constant.
51 The \fBnet_getmtu()\fR function returns -1 if the network protocol does not
52 support this feature and otherwise returns the current MTU of the network
57 The \fBnet_getmtu()\fR function may be called from user, kernel, or interrupt
