The sqlite3_autovacuum_pages(D,C,P,X) interface registers a callback function C that is invoked prior to each autovacuum of the database file.

# EVIDENCE-OF: R-08782-14491 The sqlite3_autovacuum_pages(D,C,P,X) # interface registers a callback function C that is invoked prior to # each autovacuum of the database file.
R-00160-62826-06599-62604-50169-49638-00739-38455 tcl slt th3 src
The callback is passed a copy of the generic data pointer (P), the schema-name of the attached database that is being autovacuumed, the size of the database file in pages, the number of free pages, and the number of bytes per page, respectively.

If the callback returns zero, then no autovacuum happens.

If the value returned is greater than or equal to the number of free pages, then a complete autovacuum happens.

If there are multiple ATTACH-ed database files that are being modified as part of a transaction commit, then the autovacuum pages callback is invoked separately for each file.

The X parameter to sqlite3_autovacuum_pages(D,C,P,X) is an optional destructor for the P parameter.

If X is not NULL, then X(P) is invoked whenever the database connection closes or when the callback is overwritten by another invocation of sqlite3_autovacuum_pages().

If the callback argument (C) to sqlite3_autovacuum_pages(D,C,P,X) is a NULL pointer, then the autovacuum steps callback is cancelled.
