/* When compiling a DLL for Windows, the exported symbols have to be declared
|
| 95 |
using some MS magic. I found some useful information on this web page:
|
| 96 |
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
|
| 97 |
information there, using __declspec(dllexport) without "extern" we have a
|
| 98 |
definition; with "extern" we have a declaration. The settings here override the
|
| 99 |
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
|
| 100 |
which is all that is needed for applications (they just import the symbols). We
|
| 101 |
use:
|
| 102 |
|
| 103 |
PCRE_EXP_DECL for declarations
|
| 104 |
PCRE_EXP_DEFN for definitions of exported functions
|
| 105 |
PCRE_EXP_DATA_DEFN for definitions of exported variables
|
| 106 |
|
| 107 |
The reason for the two DEFN macros is that in non-Windows environments, one
|
| 108 |
does not want to have "extern" before variable definitions because it leads to
|
| 109 |
compiler warnings. So we distinguish between functions and variables. In
|
| 110 |
Windows, the two should always be the same.
|
| 111 |
|
| 112 |
The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
|
| 113 |
which is an application, but needs to import this file in order to "peek" at
|
| 114 |
internals, can #include pcre.h first to get an application's-eye view.
|
| 115 |
|
| 116 |
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
|
| 117 |
special-purpose environments) might want to stick other stuff in front of
|
| 118 |
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
|
| 119 |
PCRE_EXP_DATA_DEFN only if they are not already set. */

the characters so that they always use the ASCII/UTF-8 code when UTF-8 support

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.

their negation. Also, they must appear in the same order as in the opcode

corresponds to "." in DOTALL mode rather than an escape sequence. It is also

They must be contiguous, and remain in order so that the replacements can be

looked up from a table.

The final escape must be ESC_REF as subsequent values are used for

backreferences (\1, \2, \3, etc). There are two tests in the code for an escape

put in between that don't consume a character, that code will have to change.
