Changes to src/sqlite.h.in.
5616 5616 ** interface returns SQLITE_OK and fills in the non-NULL pointers in 5617 5617 ** the final five arguments with appropriate values if the specified 5618 5618 ** column exists. ^The sqlite3_table_column_metadata() interface returns 5619 5619 ** SQLITE_ERROR and if the specified column does not exist. 5620 5620 ** ^If the column-name parameter to sqlite3_table_column_metadata() is a 5621 5621 ** NULL pointer, then this routine simply checks for the existence of the 5622 5622 ** table and returns SQLITE_OK if the table exists and SQLITE_ERROR if it 5623 -** does not. 5623 +** does not. If the table name parameter T in a call to 5624 +** sqlite3_table_column_metadata(X,D,T,C,...) is NULL then the result is 5625 +** undefined behavior. 5624 5626 ** 5625 5627 ** ^The column is identified by the second, third and fourth parameters to 5626 5628 ** this function. ^(The second parameter is either the name of the database 5627 5629 ** (i.e. "main", "temp", or an attached database) containing the specified 5628 5630 ** table or NULL.)^ ^If it is NULL, then all attached databases are searched 5629 5631 ** for the table using the same algorithm used by the database engine to 5630 5632 ** resolve unqualified table references.
