** CAPI3REF: Database Connection Client Data
** METHOD: sqlite3
**
** These functions are used to associate one or more named pointers
** with a [database connection].
** A call to sqlite3_set_clientdata(D,N,P,X) causes the pointer P
** to be attached to [database connection] D using name N. Subsequent
** calls to sqlite3_get_clientdata(D,N) will return a copy of pointer P
** or a NULL pointer if there were no prior calls to
** sqlite3_set_clientdata() with the same values of D and N.
** Names are compared using strcmp() and are thus case sensitive.
**
** If P and X are both non-NULL, then the destructor X is invoked with
** argument P on the first of the following occurrences:
** <ul>
** <li> An out-of-memory error occurs during the call to
** sqlite3_set_clientdata() which attempts to register pointer P.
** <li> A subsequent call to sqlite3_set_clientdata(D,N,P,X) is made
** with the same D and N parameters.
** <li> The database connection closes. SQLite does not make any guarantees
** about the order in which destructors are called, only that all
** destructors will be called exactly once at some point during the
** database connection closing process.
** </ul>
**
** SQLite does not do anything with client data other than invoke
** destructors on the client data at the appropriate time. The intended
** use for client data is to provide a mechanism for wrapper libraries
** to store additional information about an SQLite database connection.
**
** There is no limit (other than available memory) on the number of different
** client data pointers (with different names) that can be attached to a
** single database connection. However, the implementation is optimized
** for the case of having only one or two different client data names.
** Applications and wrapper libraries are discouraged from using more than
** one client data name each.
**
** There is no way to enumerate the client data pointers
** associated with a database connection. The N parameter can be thought
** of as a secret key such that only code that knows the secret key is able
** to access the associated data.
**
** Security Warning: These interfaces should not be exposed in scripting
** languages or in other circumstances where it might be possible for an
** an attacker to invoke them. Any agent that can invoke these interfaces
** can probably also take control of the process.
**
** Database connection client data is only available for SQLite
** version 3.44.0 ([dateof:3.44.0]) and later.
