typedef void (*sqlite3_destructor_type)(void*); #define SQLITE_STATIC ((sqlite3_destructor_type)0) #define SQLITE_TRANSIENT ((sqlite3_destructor_type)-1)
These are special values for the destructor that is passed in as the final argument to routines like sqlite3_result_blob(). R-31518-37056:[If the destructor argument is SQLITE_STATIC, it means that the content pointer is constant and will never change. ] It does not need to be destroyed. R-15807-22461:[The SQLITE_TRANSIENT value means that the content will likely change in the near future and that SQLite should make its own private copy of the content before returning. ]
The typedef is necessary to work around problems in certain C++ compilers.
