# This file attempts to check the behavior of the SQLite library in

# an out-of-memory situation. When compiled with -DSQLITE_DEBUG=1,
|
|
# the SQLite library accepts a special command (sqlite3_memdebug_fail N C)
|
|
# which causes the N-th malloc to fail. This special feature is used
|
|
# to see what happens in the library if a malloc were to really fail
|
|
# due to an out-of-memory situation.
