* mk_err_msg                                                                 *
******************************************************************************
* Mk_err_msg() formats an error message. The formatted error message can be  *
* put in the error log file. The error log file is /usr/db/ERROR.LOG.        *
* ERROR.LOG stores formatted error messages. When a process crashes, it      *
* should put an error message in ERROR.LOG.                                  *
*                                                                            *
* The pname argument is a pointer to a string that holds the name of the     *
* process that is generating the error message.  The errmsg argument is a    *
* pointer to a string that holds the error message.  The error message       *
* string may be up to 75 characters. The err argument is a pointer to a      *
* structure of type error_message. Err will contain the formatted error      *
* message. Err is a record in ERROR.LOG; once formatted, err can be written  *
* to ERROR.LOG (using dbwrite).                                              *
*                                                                            *
* Err is a two line message that is put into the ERROR.LOG file. The first   *
* line of err is a dat/time and program name (pname). The second line is a   *
* 75 character message (errmsg). You do not need to put carriage returns or  *
* line feeds in pname and errmsg.                                            *
