Does MySQL open the .frm file when opening a table?

[Martijn van den Burg]

Hi list,

If MySQL opens a table, does it also need open the corresponding table format 
file?
If it does, does it increment open_files?

In other words: does opening a MyISAM table take three file handles, and 
opening a InnoDB table two (assuming the tablespace file isn't opened yet)?


Kind regards,
