Load a message database
ApMsgDBase_t *ApLoadMessageDB( ApMsgDBase_t *db, const char *name );
This function loads the message database with the given name. It searches for the file based on the value of the ABLPATH and the current language:
Note that in an application that uses PhAB DLLs, this function performs the language search based on the location of the executable or DLL associated with the current context. If there's no current context, a lookup that would search the directory of an executable or DLL is skipped.
A pointer to the new database, or NULL if it couldn't be opened.
