status.i4.v = email_send_message(user.i1a.r, subject.i1a.r,
					 message.i1a.r, file_name.i1a.r)

	This function aids the programmer in sending email message to users.
	All arguments must be specified.  The function sends either a simple
	message string or a file.  One argument must be NULL.

	user		ASCII string containing destination user name(s)
			(Multiple names should be separated by commas.)
	subject		ASCII string containing mail subject
	message		ASCII string containing mail message
			(Specify a value of NULL if specifying a file
			 with the file argument.)
	file_name	ASCII string containing mail file name
			(Multiple files should be separated by spaces.
			 Specify a value of NULL if specifying the message
			 with the message argument.)

	Note: to send only non-encoded plain text files, pass the file_name
	      argument as usual, but pass any non-null value (like (char*) TRUE)
	      for the message argument.  Then it will send files as plain
	      text messages.

	This function returns status values as follows:

	OK			success
	CLIB_GENERR		mail message failed

	This function requires the following include files:

	cnsparam_h, clib_h, ssdef_h
