size_t
ksql_stmt_bytes(struct ksqlstmt *stmt, size_t column);

double
ksql_stmt_double(struct ksqlstmt *stmt, size_t column);

int64_t
ksql_stmt_int(struct ksqlstmt *stmt, size_t column);

const char *
ksql_stmt_str(struct ksqlstmt *stmt, size_t column);

DESCRIPTION

These functions functions return results following ksql_stmt_step(3). They all accept stmt, the statement allocated with ksql_stmt_alloc(3); and the column to query, which starts at zero. The results are not defined for a statement without a resulting row or for columns beyond the prepared statement.

The ksql_stmt_str() and ksql_stmt_blob() functions return memory tha tmust be copied prior to subsequent ksql_stmt_step(3), ksql_stmt_reset(3), or ksql_stmt_free(3).
