PCRE(3)                                                   PCRE(3)



NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include 

       pcre_extra *pcre_study(const pcre *code, int options,
            const char **errptr);


DESCRIPTION

       This  function studies a compiled pattern, to see if addi-
       tional information can be extracted that  might  speed  up
       matching. Its arguments are:

         code       A compiled regular expression
         options    Options for pcre_study()
         errptr     Where to put an error message

       If the function returns NULL, either it could not find any
       additional information, or there was  an  error.  You  can
       tell  the  difference by looking at the error value. It is
       NULL in first case.

       There are currently no options defined; the value  of  the
       second argument should always be zero.

       There  is  a  complete  description of the PCRE API in the
       pcreapi page.
