.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.B int pcre_config(int \fIwhat\fP, void *\fIwhere\fP);
.PP
.B int pcre16_config(int \fIwhat\fP, void *\fIwhere\fP);
.PP
.B int pcre32_config(int \fIwhat\fP, void *\fIwhere\fP);
.
.SH DESCRIPTION
.rs
.sp
This function makes it possible for a client program to find out which optional
features are available in the version of the PCRE library it is using. The
arguments are as follows:
.sp
\fIwhat\fP A code specifying what information is required
\fIwhere\fP Points to where to put the data
.sp
The \fIwhere\fP argument must point to an integer variable, except for
PCRE_CONFIG_MATCH_LIMIT and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must
point to an unsigned long integer. The available codes are:
.sp
PCRE_CONFIG_JIT Availability of just-in-time compiler
support (1=yes 0=no)
PCRE_CONFIG_JITTARGET String containing information about the
target architecture for the JIT compiler,
or NULL if there is no JIT support
PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4
PCRE_CONFIG_PARENS_LIMIT Parentheses nesting limit
PCRE_CONFIG_MATCH_LIMIT Internal resource limit
PCRE_CONFIG_MATCH_LIMIT_RECURSION
Internal recursion depth limit
PCRE_CONFIG_NEWLINE Value of the default newline sequence:
13 (0x000d) for CR
10 (0x000a) for LF
3338 (0x0d0a) for CRLF
-2 for ANYCRLF
-1 for ANY
PCRE_CONFIG_BSR Indicates what \eR matches by default:
0 all Unicode line endings
1 CR, LF, or CRLF only
PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
Threshold of return slots, above which
\fBmalloc()\fP is used by the POSIX API
PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap)
PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes
0=no); option for \fBpcre16_config()\fP
PCRE_CONFIG_UTF32 Availability of UTF-32 support (1=yes
0=no); option for \fBpcre32_config()\fP
PCRE_CONFIG_UTF8 Availability of UTF-8 support (1=yes 0=no);
option for \fBpcre_config()\fP
PCRE_CONFIG_UNICODE_PROPERTIES
Availability of Unicode property support
(1=yes 0=no)
.sp
The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error
is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to
\fBpcre_config()\fP, if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to
\fBpcre16_config()\fP, or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to
\fBpcre32_config()\fP.
.P
There is a complete description of the PCRE native API in the
.\" HREF
\fBpcreapi\fP
.\"
page and a description of the POSIX API in the
.\" HREF
\fBpcreposix\fP
.\"
page.
