/* 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 pcre2.h (which is included below); it defines only PCRE2_EXP_DECL,

|
|
use:
|

|
|
PCRE2_EXP_DECL for declarations
|
|
PCRE2_EXP_DEFN for definitions
|

The reason for wrapping this in #ifndef PCRE2_EXP_DECL is so that pcre2test,

which is an application, but needs to import this file in order to "peek" at
|

internals, can #include pcre2.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 PCRE2_EXP_DEFN

/* If PCRE2 is to support UTF-8 on EBCDIC platforms, we cannot use normal

|
character constants like '*' because the compiler would emit their EBCDIC code,
|
|
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 PCRE2 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 PCRE2_UTF 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. */

characters, a common practice has been to use its NL (0x15) character as the

line terminator in C-like processing environments. However, sometimes the LF

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

PCRE2 defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25

Negative numbers are used to encode a backreference (\1, \2, \3, etc.) in

check_escape(). There are tests in the code for an escape greater than ESC_b

types that consume characters. If any new escapes are put in between that don't

consume a character, that code will have to change. */
