SYNOPSIS
     #include <sys/mac.h>
     #include <t6net.h>

     int tsix_recvfrom_mac(int fd, void *buf, int len, int flags,
			   void *from, int *fromlen, mac_t *lbl);

DESCRIPTION

     tsix_recvfrom_mac is successful, that MAC label will be pointed to by
     lbl.

RETURN VALUES
     If _SC_IP_SECOPTS is not in effect, tsix_recvfrom_mac always returns
     success.

     tsix_recvfrom_mac returns the number of bytes received, otherwise -1 and
     the global error value errno is assigned the appropriate error code.
