+** 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.

+** 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.
+**
+** See also: [sqlite3_set_auxdata()] and [sqlite3_get_auxdata()].
