MEMSTATUS

Enables or disables the collection of memory allocation statistics. When memory allocation statistics are disabled, the following SQLite interfaces become non-operational:

• sqlite3_hard_heap_limit64()

• sqlite3_memory_used()

• sqlite3_memory_highwater()

• sqlite3_soft_heap_limit64()

• sqlite3_status64()

Memory allocation statistics are enabled by default unless SQLite is compiled with SQLITE_DEFAULT_MEMSTATUS=0 in which case memory allocation statistics are disabled by default.
