Re: Information wanted for UCX$C_AUXS
This is used to hand off a connection from the process that listens for the incoming connection to the process that will service the connections requests. In the Unix world the process that listens for the connection would generally fork() to accept the incoming connection, then process the new connection in the forked child.
VMS uses a different mechanism because it does not implement the Unix fork().

Re: Information wanted for UCX$C_AUXS
I would like to add few more info.
As other members said, UCX$C_AUXS is one of the argument passed to the socket () routine and VMS system routines (SYS$xxxx).
usuage:
SYS$QIOW( EFN$C_ENF,channel, IO$_SETMODE,
&iosb, 0, 0, &sockchar, 0, 0, 0, 0,0)
SOCKET(UCX$C_AUXS, stream_type_file, and comm_protocol).
the Ist arg in socket routine and 7th arg in sys$qiow routine specifies the address family, this address can be referenced in subsequent operations in the send and receive routines. UCX$C_AUXS is passed as arg whenever the auxiliary server creates a process in response to the incoming network service with LISTEN flag. The 7th arg in sys$qiow() is structure with the following 3 members.
sockchar.prot = protocol_type;
sockchar.type = stream_type_file;/*C file*/
sockchar.af = UCX$C_AUXS;

Re: Information wanted for UCX$C_AUXS
Just came across this question and thought a COBOL (or any non-C) example might be useful for those who want $QIO access to the Auxillary Server (INETd).
