## SQLite C Interface

## SQL Function Context Object

>     typedef struct sqlite3_context sqlite3_context;

The context in which an SQL function executes is stored in an sqlite3_context object. A pointer to an sqlite3_context object is always first parameter to application-defined SQL functions. The application-defined SQL function implementation will pass this pointer through into calls to sqlite3_result(), sqlite3_aggregate_context(), sqlite3_user_data(), sqlite3_context_db_handle(), sqlite3_get_auxdata(), and/or sqlite3_set_auxdata().

Methods:
sqlite3_aggregate_context sqlite3_context_db_handle sqlite3_get_auxdata sqlite3_result_blob sqlite3_result_blob64 sqlite3_result_double sqlite3_result_error sqlite3_result_error16 sqlite3_result_error_code | sqlite3_result_error_nomem sqlite3_result_error_toobig sqlite3_result_int sqlite3_result_int64 sqlite3_result_null sqlite3_result_subtype sqlite3_result_text sqlite3_result_text16 sqlite3_result_text16be | sqlite3_result_text16le sqlite3_result_text64 sqlite3_result_value sqlite3_result_zeroblob sqlite3_result_zeroblob64 sqlite3_set_auxdata sqlite3_user_data
