Finally, makeheaders also includes a &#8220;<code>-doc</code>&#8221; option.
This command line option prevents makeheaders from generating any
headers at all.
Instead, makeheaders will write to standard output
information about every definition and declaration that it encounters
in its scan of source files.
The information output includes the type of the definition or
declaration and any comment that preceeds the definition or
declaration.
The output is in a format that can be easily parsed, and is
intended to be read by another program that will generate
documentation about the program.
We'll talk more about this feature later.

The structure of a .c file intented for use with makeheaders is very
simple.
All you have to do is add a single &#8220;<code>#include</code>&#8221; to the
top of the file that sources the header file that makeheaders will generate.
Hence, the beginning of a source file named &#8220;<code>alpha.c</code>&#8221;
might look something like this:

<h3>3.3 How To Avoid Having To Write Any Header Files</h3>

<p>
In my experience, large projects work better if all of the manually
written code is placed in .c files and all .h files are generated
automatically.
This is slightly different for the traditional C method of placing
the interface in .h files and the implementation in .c files, but
it is a refreshing change that brings a noticable improvement to the
coding experience.
Others, I believe, share this view since I've
noticed recent languages (ex: java, tcl, perl, awk) tend to
support the one-file approach to coding as the only option.

That isn't the complete truth, actually.
The semantics of C are such that once an object becomes visible
outside of a single source file, it is also visible to any user
of the library that is made from the source file.
Makeheaders can not prevent outsiders for using non-exported resources,
but it can discourage the practice by refusing to provide prototypes
and declarations for the services it does not want to export.
Thus the only real effect of the making an object exportable is
to include it in the output makeheaders generates when it is run
using the -H command line option.
This is not a perfect solution, but it works well in practice.

** When the SQLITE_DBCONFIG_TRUSTED_SCHEMA option is disabled, SQLite

** <li> Prohibit the use of SQL functions inside triggers, views,
** CHECK constraints, DEFAULT VALUEs, index definitions, and/or
** generated columns unless those functions are tagged

** <li> Pohibit the use of virtual tables inside of triggers and/or views

**
** Lookaside buffers are initially held on the pInit list.  As they are
** used and freed, they are added back to the pFree list.  New allocations
** come off of pFree first, then pInit as a fallback.  This dual-list
** allows use to compute a high-water mark - the maximum number of allocations
** outstanding at any point in the past - by subtracting the number of
** allocations on the pInit list from the total number of allocations.
**
** Enhancement on 2019-12-12:  Two-size-lookaside
** The default lookaside configuration is 100 slots of 1200 bytes each.
** The larger slot sizes are important for performance, but they waste
** a lot of space, as most lookaside allocations are less than 128 bytes.
** The two-size-lookaside enhancement breaks up the lookaside allocation
** into two pools:  One of 128-byte slots and the other of the default size
** (1200-byte) slots.   Allocations are filled from the small-pool first,
** failing over to the full-size pool if that does not work.  Thus more
** lookaside slots are available while also using less memory.
** This enhancement can be omitted by compiling with
** SQLITE_OMIT_TWOSIZE_LOOKASIDE.

/* Opcode:  ReleaseReg   P1 P2 P3 * P5
** Synopsis: release r[P1@P2] mask P3
**
** Release registers from service.  Any content that was in the
** the registers is unreliable after this opcode completes.
**
** The registers released will be the P2 registers starting at P1,
** except if bit ii of P3 set, then do not release register P1+ii.
** In other words, P3 is a mask of registers to preserve.
**
** Releasing a register clears the Mem.pScopyFrom pointer.  That means
** that if the content of the released register was set using OP_SCopy,
** a change to the value of the source register for the OP_SCopy will no longer
** generate an assertion fault in sqlite3VdbeMemAboutToChange().
**
** If P5 is set, then all released registers have their type set
** to MEM_Undefined so that any subsequent attempt to read the released
** register (before it is reinitialized) will generate an assertion fault.
**
** P5 ought to be set on every call to this opcode.
** However, there are places in the code generator will release registers
** before their are used, under the (valid) assumption that the registers
** will not be reallocated for some other purpose before they are used and
** hence are safe to release.
**
** This opcode is only available in testing and debugging builds.  It is
** not generated for release builds.  The purpose of this opcode is to help
** validate the generated bytecode.  This opcode does not actually contribute
** to computing an answer.
