PCRE(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 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.
