PCRE_CONFIG(3)         C LIBRARY FUNCTIONS         PCRE_CONFIG(3)

NAME

     PCRE - Perl-compatible regular expressions

SYNOPSIS

     #include <pcre.h>

     int pcre_config(int what, void *where);

     int pcre16_config(int what, void *where);

     int pcre32_config(int what, void *where);

DESCRIPTION

     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:

       what     A code specifying what information is required
       where    Points to where to put the data

     The where argument must point to an integer variable, except
     for                                 PCRE_CONFIG_MATCH_LIMIT,
     PCRE_CONFIG_MATCH_LIMIT_RECURSION,                       and
     PCRE_CONFIG_PARENS_LIMIT,  when it must point to an unsigned
     long integer, and for PCRE_CONFIG_JITTARGET,  when  it  must
     point to a const char*.  The available codes are:

       PCRE_CONFIG_JIT            Availability  of   just-in-time

       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  \R  matches  by
     default:

     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    pcre_config(),    if
     PCRE_CONFIG_UTF8   or   PCRE_CONFIG_UTF32   is   passed   to
     pcre16_config(), or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16
     is  passed to pcre32_config().  There is a complete descrip-
     tion of the PCRE native  API  in  the  pcreapi  page  and  a
     description of the POSIX API in the pcreposix page.
