Function Documentation

SdbpAddStringToTable()

BOOL SdbpAddStringToTable	(	struct SdbStringHashTable **	table,
		const WCHAR *	str,
		TAGID *	pTagid
	)

Find an entry in the stringtable, or allocate it when an entry could not be found.

• When the string specified does not yet exist, a new entry will be added to the table, and the pTagid specified will be associated with this string.
• When the string specified does already exist, the TAGID associated with this string will be returned in pTagid.

Parameters

[in]	table	Pointer to table pointer, will be allocated when needed.
[in]	str	The string to search for
[in,out]	pTagid	the data written (in bytes)

Returns

TRUE if the string was added to the table, FALSE if it already existed
