I'm not sure if you are asking in general or specifically about this case. In general, such naming is usually done to make it clear that routines like __get_host_no_from_hwaddress() are not called directory by external users.Also note that this function is static. This sort of naming is usually done, as well, to make it clear that there is an external interface (some name without underscores at the start) that is meant to be called externally and calls this function. In this case it's iscsi_sysfs_get_host_no_from_hwaddress(). I'm guessing (because I wasn't around back then) that the "__*" functions were copied from libudev at one time, but that is just a SWAG. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
