Confusion On Sqlite3 Struct In Sqlite3 Source Code

In the function static int sqlite3Prepare( sqlite3 *db, /* Database handle. */ const char *zSql, /* UTF-8 encoded SQL statement. */ int nBytes,

Solution 1:

sqlite3 is not a fake struct; the sqlite.h file just does not define its body.

Its definition is in the sqliteInt.h file (which is also part of the sqlite3.c amalgamation):

/*
** Each database connection is an instance of the following structure.
*/structsqlite3 {
  sqlite3_vfs *pVfs;            /* OS Interface */structVdbe *pVdbe;           /* List of active virtual machines */
  CollSeq *pDfltColl;           /* The default collating sequence (BINARY) */
  ...
  u8 mallocFailed;              /* True if we have seen a malloc failure */
  ...
