/* On Unix systems config.in is converted by configure into config.h. PCRE is
3
written in Standard C, but there are a few non-standard things it can cope
4
with, allowing it to run on SunOS4 and other "close to standard" systems.
6
On a non-Unix system you should just copy this file into config.h, and set up
7
the macros the way you need them. You should normally change the definitions of
8
HAVE_STRERROR and HAVE_MEMMOVE to 1. Unfortunately, because of the way autoconf
9
works, these cannot be made the defaults. If your system has bcopy() and not
10
memmove(), change the definition of HAVE_BCOPY instead of HAVE_MEMMOVE. If your
11
system has neither bcopy() nor memmove(), leave them both as 0; an emulation
12
function will be used. */
14
/* If you are compiling for a system that uses EBCDIC instead of ASCII
15
character codes, define this macro as 1. On systems that can use "configure",
16
this can be done via --enable-ebcdic. */
22
/* If you are compiling for a system that needs some magic to be inserted
23
before the definition of an exported function, define this macro to contain the
24
relevant magic. It apears at the start of every exported function. */

/* Define to empty if the "const" keyword does not work. */

/* Define to "unsigned" if <stddef.h> doesn't define size_t. */
36
/* The following two definitions are mainly for the benefit of SunOS4, which
37
doesn't have the strerror() or memmove() functions that should be present in
38
all Standard C libraries. The macros HAVE_STRERROR and HAVE_MEMMOVE should
39
normally be defined with the value 1 for other systems, but unfortunately we
40
can't make this the default because "configure" files generated by autoconf
41
will only change 0 to 1; they won't change 1 to 0 if the functions are not

/* There are some non-Unix systems that don't even have bcopy(). If this macro
48
is false, an emulation is used. If HAVE_MEMMOVE is set to 1, the value of
49
HAVE_BCOPY is not relevant. */

/* The value of NEWLINE determines the newline character. The default is to
54
leave it up to the compiler, but some sites want to force a particular value.
55
On Unix systems, "configure" can be used to override this default. */
61
/* The value of LINK_SIZE determines the number of bytes used to store
62
links as offsets within the compiled regex. The default is 2, which allows for
63
compiled patterns up to 64K long. This covers the vast majority of cases.
64
However, PCRE can also be compiled to use 3 or 4 bytes instead. This allows for
65
longer patterns in extreme cases. On Unix systems, "configure" can be used to
66
override this default. */
72
/* The value of MATCH_LIMIT determines the default number of times the match()
73
function can be called during a single execution of pcre_exec(). (There is a
74
runtime method of setting a different limit.) The limit exists in order to
75
catch runaway regular expressions that take for ever to determine that they do
76
not match. The default is set very large so that it does not accidentally catch
77
legitimate cases. On Unix systems, "configure" can be used to override this
81

/* When calling PCRE via the POSIX interface, additional working storage is
85
required for holding the pointers to capturing substrings because PCRE requires
86
three integers per substring, whereas the POSIX interface provides only two. If
87
the number of expected substrings is small, the wrapper function uses space on
88
the stack, because this is faster than using malloc() for each call. The
89
threshold above which the stack is no longer use is defined by POSIX_MALLOC_
90
THRESHOLD. On Unix systems, "configure" can be used to override this default.

/* PCRE uses recursive function calls to handle backtracking while matching.
98
This can sometimes be a problem on systems that have stacks of limited size.
99
Define NO_RECURSE to get a version that doesn't use recursion in the match()
100
function; instead it creates its own stack by steam using pcre_recurse_malloc
101
to get memory. For more detail, see comments and other stuff just above the
102
match() function. On Unix systems, "configure" can be used to set this in the
103
Makefile (use --disable-stack-for-recursion). */
