pcre16_get_substring


SYNOPSIS

       #include <pcre.h>

       int pcre_get_substring(const char *subject, int *ovector,
            int stringcount, int stringnumber,
            const char **stringptr);

       int pcre16_get_substring(PCRE_SPTR16 subject, int *ovector,
            int stringcount, int stringnumber,
            PCRE_SPTR16 *stringptr);

DESCRIPTION

       This is a convenience function for extracting a captured substring. The
       arguments are:

         subject       Subject that has been successfully matched
         ovector       Offset vector that pcre[16]_exec() used
         stringcount   Value returned by pcre[16]_exec()
         stringnumber  Number of the required substring
         stringptr     Where to put the string pointer

       The memory in which the substring is  placed  is  obtained  by  calling
       pcre[16]_malloc().  The  convenience function pcre[16]_free_substring()
       can be used to free it when it is no longer needed. The  yield  of  the
       function  is the length of the substring, PCRE_ERROR_NOMEMORY if suffi-
       cient memory could not be obtained, or  PCRE_ERROR_NOSUBSTRING  if  the
       string number is invalid.

       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.
