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]tablePointer to table pointer, will be allocated when needed.
[in]strThe string to search for
[in,out]pTagidthe data written (in bytes)
Returns
TRUE if the string was added to the table, FALSE if it already existed
