tsix_sendto_mac(3N)

NAME
     tsix_sendto_mac - send a message with a specified MAC label

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

     int tsix_sendto_mac(int fd, const void *msg, int len,
                         int flags, void *to, int tolen,
                         mac_t lbl);

DESCRIPTION
     tsix_sendto_mac transmits a message to another socket, temporarily
     overriding the default MAC label associated with that message with the
     MAC label pointed to by lbl . tsix_sendto_mac is otherwise identical to
     sendto(2).

     If _SC_CAP is in effect, a process calling this function must have
     CAP_MAC_UPGRADE , CAP_MAC_DOWNGRADE , CAP_MAC_RELABEL_OPEN , and
     CAP_MAC_MLD capabilities in the permitted vector of its capability set.

     If _SC_IP_SECOPTS is not in effect, tsix_sendto_mac always returns
     success.

RETURN VALUES
     tsix_sendto_mac returns the number of bytes sent, or -1 if an error
     occurred.
