+
+  SYNOPSIS
+    mi_report_error()
+    file_name                   Name of table file (e.g. index_file_name).
+    errcode                     Error number.
+
+  DESCRIPTION
+    This function supplies my_error() with a table name. Most error
+    messages need one. Since string arguments in error messages are limited
+    to 64 characters by convention, we ensure that in case of truncation,
+    that the end of the index file path is in the message. This contains
+    the most valuable information (the table name and the database name).
+
+  RETURN
+    void
