/* 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:
|
| 86 |
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
|
| 87 |
information there, using __declspec(dllexport) without "extern" we have a
|
| 88 |
definition; with "extern" we have a declaration. The settings here override the
|
| 89 |
setting in pcre2.h (which is included below); it defines only PCRE2_EXP_DECL,
|
| 90 |
which is all that is needed for applications (they just import the symbols). We
|
| 91 |
use:
|
| 92 |
|
| 93 |
PCRE2_EXP_DECL for declarations
|
| 94 |
PCRE2_EXP_DEFN for definitions
|
| 95 |
|
| 96 |
The reason for wrapping this in #ifndef PCRE2_EXP_DECL is so that pcre2test,
|
| 97 |
which is an application, but needs to import this file in order to "peek" at
|
| 98 |
internals, can #include pcre2.h first to get an application's-eye view.
|
| 99 |
|
| 100 |
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
|
| 101 |
special-purpose environments) might want to stick other stuff in front of
|
| 102 |
exported symbols. That's why, in the non-Windows case, we set PCRE2_EXP_DEFN
|
| 103 |
only if it is not already set. */

NOTACHAR (which is 0xffffffff).

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
|
| 594 |
the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
|
| 595 |
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
|
| 601 |
would need different lookups depending on whether PCRE2_UTF was set or not.
|
| 602 |
This would make it impossible to use characters in switch/case statements,

| 603 |
which would reduce performance. For a theoretical use (which nobody has asked
|
| 604 |
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
