There's no problem. I would like to propose inlining of several pretty often used functions: sqlite3BtreeGetPageSize sqlite3BtreePager sqlite3PagerBackupPtr sqlite3PagerRef sqlite3PagerPageRefcount sqlite3PagerGetData sqlite3PagerGetExtra sqlite3PagerIsreadonly sqlite3PagerRefcount sqlite3PagerFilename sqlite3PagerVfs sqlite3PagerFile sqlite3PagerJournalname sqlite3PagerNosync sqlite3PagerTempSpace sqlite3PagerIsMemdb For instance, I introduced a compiler flag named INLDEF and for each ot these functions I issued: in the declaration section:
    #ifdef INLDEF
    # define sqlite3BtreeGetPageSize(a) (a)->pBt->pageSize
    SQLITE_PRIVATE INL int sqlite3BtreeGetPageSize(Btree*);

and in the implementation section:

    #ifndef INLDEF
    SQLITE_PRIVATE int sqlite3BtreeGetPageSize(Btree *p){
      return p->pBt->pageSize;

Best regards: Chris

Modern C compilers do this kind of inlining automatically. There is no need to complicate the code.
