       PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       void pcre2_substring_free(PCRE2_UCHAR *buffer);


       This  is  a  convenience  function  for  freeing the memory obtained by a previous call to
       pcre2_substring_get_byname() or pcre2_substring_get_bynumber(). Its  only  argument  is  a
       pointer to the string. If the argument is NULL, the function does nothing.

       There  is  a  complete  description  of  the  PCRE2  native API in the pcre2api page and a
       description of the POSIX API in the pcre2posix page.
