PCRE_STUDY(3)							 PCRE_STUDY(3)

NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

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

DESCRIPTION

       This function studies a compiled pattern, to see if additional informa‐
       tion 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 succeeds, it returns a value  that  can	be  passed  to
       pcre_exec() via its extra argument.

       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 argu‐
       ment should always be zero.

       There is a complete description of the PCRE native API in  the  pcreapi
       page and a description of the POSIX API in the pcreposix page.
