ksql_free —
free a ksql database handle
library “ksql”
#include

enum ksqlc
ksql_free(
struct
ksql *sql);
The
ksql_free function frees a database
handle
sql, previously allocated with
ksql_alloc(3). This internally invokes
ksql_close(3) then frees all internal memory. If
the handle was allocated with
KSQL_SAFE_EXIT, the handle is removed from
the queue of handles that would be freed on exit (so it is not double-freed).
If
sql is
NULL, no action occurs.
This function is invoked from the
atexit(3) handler
if
KSQL_SAFE_EXIT was specified and the
handle was not freed prior to exiting. In this case, the
KSQL_EXIT_ON_ERR flag is temporarily
suppressed.
This returns the error code of
ksql_close(3).
