/* When compiling a DLL for Windows, the exported symbols have to be declared
using some MS magic. I found some useful information on this web page:
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
information there, using __declspec(dllexport) without "extern" we have a
definition; with "extern" we have a declaration. The settings here override the
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
which is all that is needed for applications (they just import the symbols). We
use:

  PCRE_EXP_DECL       for declarations
  PCRE_EXP_DEFN       for definitions of exported functions
  PCRE_EXP_DATA_DEFN  for definitions of exported variables

The reason for the two DEFN macros is that in non-Windows environments, one
does not want to have "extern" before variable definitions because it leads to
compiler warnings. So we distinguish between functions and variables. In
Windows, the two should always be the same.

The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
which is an application, but needs to import this file in order to "peek" at
internals, can #include pcre.h first to get an application's-eye view.

In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
special-purpose environments) might want to stick other stuff in front of
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
PCRE_EXP_DATA_DEFN only if they are not already set. */

information; I know nothing about MSVC myself). For example, something like

PCRE_CALL_CONVENTION just before their names. It is rarely needed; if not

exactly 256 items. When the character is able to contain more than 256

/* PCRE keeps offsets in its compiled code as 2-byte quantities (always stored

start of a subpattern to its alternatives and its end. The use of 2 bytes per
offset limits the size of the compiled regex to around 64K, which is big enough
for almost everybody. However, I received a request for an even bigger limit.
For this reason, and also to make the code easier to maintain, the storing and
loading of offsets from the byte string is now handled by the macros that are
defined here.

The macros are controlled by the value of LINK_SIZE. This defaults to 2 in
the config.h file, but can be overridden by using -D on the command line. This

which is different from their ASCII/UTF-8 code. Instead we define macros for
the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
is enabled. When UTF-8 support is not enabled, the definitions use character
literals. Both character and string versions of each character are needed, and
there are some longer strings as well.

This means that, on EBCDIC platforms, the PCRE library can handle either
EBCDIC, or UTF-8, but not both. To support both in the same compiled library
would need different lookups depending on whether PCRE_UTF8 was set or not.
This would make it impossible to use characters in switch/case statements,
which would reduce performance. For a theoretical use (which nobody has asked
for) in a minority area (EBCDIC platforms), this is not sensible. Any
application that did need both could compile two versions of the library, using
macros to give the functions distinct names. */

http://unicode.org/standard/reports/tr13/tr13-5.html

/* These are escaped items that aren't just an encoding of a particular data
value such as \n. They must have non-zero values, as check_escape() returns 0
for a data character.  Also, they must appear in the same order as in the
opcode definitions below, up to ESC_z. There's a dummy for OP_ALLANY because it
corresponds to "." in DOTALL mode rather than an escape sequence. It is also
used for [^] in JavaScript compatibility mode, and for \C in non-utf mode. In
non-DOTALL mode, "." behaves like \N.

The special values ESC_DU, ESC_du, etc. are used instead of ESC_D, ESC_d, etc.
when PCRE_UCP is set and replacement of \d etc by \p sequences is required.
They must be contiguous, and remain in order so that the replacements can be
looked up from a table.

Negative numbers are used to encode a backreference (\1, \2, \3, etc.) in
check_escape(). There are two tests in the code for an escape
greater than ESC_b and less than ESC_Z to detect the types that may be
repeated. These are the types that consume characters. If any new escapes are
put in between that don't consume a character, that code will have to change.

/* The real format of the start of the pcre block; the index of names and the
code vector run on as long as necessary after the end. We store an explicit
offset to the name table so that if a regex is compiled on one host, saved, and
then run on another where the size of pointers is different, all might still
be well.

The size of the structure must be a multiple of 8 bytes. For the case of
compiled-on-4 and run-on-8, we include an extra pointer that is always NULL so
that there are an even number of pointers which therefore are a multiple of 8
bytes.

It is necessary to fork the struct for the 32 bit library, since it needs to
use pcre_uint32 for first_char and req_char. We can't put an ifdef inside the
typedef because pcretest needs access to the struct of the 8-, 16- and 32-bit
variants.

*** WARNING ***
When new fields are added to these structures, remember to adjust the code in
pcre_byte_order.c that is concerned with swapping the byte order of the fields
when a compiled regex is reloaded on a host with different endianness.
*** WARNING ***
There is also similar byte-flipping code in pcretest.c, which is used for
testing the byte-flipping features. It must also be kept in step.
