/* On Unix-like systems config.h.in is converted by "configure" into config.h.
|
|
Some other environments also support the use of "configure". PCRE is written in
|
|
Standard C, but there are a few non-standard things it can cope with, allowing
|
|
it to run on SunOS4 and other "close to standard" systems.
|
|
|
|
If you are going to build PCRE "by hand" on a system without "configure" you
|
|
should copy the distributed config.h.generic to config.h, and then set up the
|
|
macro definitions the way you need them. You must then add -DHAVE_CONFIG_H to
|
|
all of your compile commands, so that config.h is included at the start of
|
|
every source.
|
|
|
|
Alternatively, you can avoid editing by using -D on the compiler command line
|
|
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H.
|
|
|
|
PCRE uses memmove() if HAVE_MEMMOVE is set to 1; otherwise it uses bcopy() if
|
|
HAVE_BCOPY is set to 1. If your system has neither bcopy() nor memmove(), set
|
|
them both to 0; an emulation function will be used. */])

allows for compiled patterns up to 64K long. This covers the vast

majority of cases. However, PCRE can also be compiled to use 3 or 4

|
|
PCRE requires three integers per substring, whereas the POSIX
|
|
interface provides only two. If the number of expected substrings is
|
|
small, the wrapper function uses space on the stack, because this is

|
faster than using malloc() for each call. The threshold above which

The value of MATCH_LIMIT determines the default number of times the

internal match() function can be called during a single execution of

|
pcre_exec(). There is a runtime interface for setting a different
|
|
limit. The limit exists in order to catch runaway regular
|
|
expressions that take for ever to determine that they do not match.
|
|
The default is set very large so that it does not accidentally catch

legitimate cases. On systems that support it, "configure" can be

The above limit applies to all calls of match(), whether or not they

increase the recursion depth. In some environments it is desirable
|
|
to limit the depth of recursive calls of match() more strictly, in
|
|
order to restrict the maximum amount of stack (or heap, if
|
|
NO_RECURSE is defined) that is used. The value of
|
|
MATCH_LIMIT_RECURSION applies only to recursive calls of match(). To
|
|
have any useful effect, it must be less than the value of
|
|
MATCH_LIMIT. The default is to use the same value as MATCH_LIMIT.

There is a runtime method for setting a different limit. On systems
