++Get or set the congestion-control algorithm for this socket.
++The
++.I optval
++argument is a pointer to a character-string buffer.
++
++For
++.BR getsockopt ()
++.I *optlen
++specifies the amount of space available in the buffer pointed to by
++.IR optval ,
++which should be at least 16 bytes (defined by the kernel-internal constant
++.BR TCP_CA_NAME_MAX ).
++On return, the buffer pointed to by
++.I optval
++is set to a null-terminated string containing the name of the
++congestion-control algorithm for this socket, and
++.I *optlen
++is set to the minimum of its original value and
++.BR TCP_CA_NAME_MAX .
++If the value passed in
++.I *optlen
++is too small, then the string returned in
++.I *optval
++is silently truncated, and no terminating null byte is added.
++If an empty string is returned, then the socket is using the default
++congestion-control algorithm, determined as described under
++.I tcp_congestion_control
++above.
++
++For
++.BR setsockopt ()
++.I optlen
++specifies the length of the congestion-control algorithm name
++contained in the buffer pointed to by
++.IR optval ;
++this length need not include any terminating null byte.
++The algorithm "reno" is always permitted;
++other algorithms may be available, depending on kernel configuration.
++Possible errors from
++.BR setsockopt ()
++include:
++algorithm not found/available
++.RB ( ENOENT );
++setting this algorithm requires the
++.B CAP_NET_ADMIN
++capability
++.RB ( EPERM );
++and failure getting kernel module
++.RB ( EBUSY ).
