Additional fields may be appended to this ** object when the iVersion value is increased. Note that the structure ** of the sqlite3_vfs object changes in the transaction between ** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not ** modified. ** ** The szOsFile field is the size of the subclassed [sqlite3_file] ** structure used by this VFS. mxPathname is the maximum length of ** a pathname in this VFS. ** ** Registered sqlite3_vfs objects are kept on a linked list formed by ** the pNext pointer. The [sqlite3_vfs_register()] ................................................................................ ** operation before closing the connection. This option may be used to ** override this behaviour. The first parameter passed to this operation ** is an integer - non-zero to disable checkpoints-on-close, or zero (the ** default) to enable them.

/****************************************************************************** ** This file is an amalgamation of many separate C source files from SQLite ** version 3.22.0. By combining all the individual C code files into this ** single large file, the entire code can be compiled as a single translation ** unit.
