int dlt_logstorage_create_keys	(	char *	appids,
		char *	ctxids,
		char **	keys,
		int *	num_keys
	)

dlt_logstorage_create_keys

Create keys for hash table

From each section [filter] in offline logstorage configuration file, we receive application and context id strings. Application and context id can consist of

• a 4char long name
• a comma separated list of ids
• a wildcard: .*

Not allowed is the combination of application id and context id set to wildcard. This will be rejected.

If lists given for application and/or context id, all possible combinations are returned as keys in a form "[appid][ctxid], e.g. "APP1:CTX1". If wildcards are used, the non-wildcard value becomes the key, e.g. "APP1:" or ":CTX2".

Parameters

dlt_logstorage_read_list_of_names

Evaluate app and ctx names given in config file and create a list of names acceptable by DLT Daemon When using SET_APPLICATION_NAME and SET_CONTEXT_NAME there is no constraint that these names have max 4 characters. Internally, these names are cutted down to max 4 chars. To have create valid keys, the internal representation of these names has to be considered. Therefore, a given configuration of "AppLogName = App1,Application2,A3" will be stored as "App1,Appl,A3".
