NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS


       #include <pcre.h>

       int pcre_copy_substring(const char *subject, int *ovector,
            int stringcount, int stringnumber, char *buffer,
            int buffersize);

       int pcre16_copy_substring(PCRE_SPTR16 subject, int *ovector,
            int stringcount, int stringnumber, PCRE_UCHAR16 *buffer,
            int buffersize);

       int pcre32_copy_substring(PCRE_SPTR32 subject, int *ovector,
            int stringcount, int stringnumber, PCRE_UCHAR32 *buffer,
            int buffersize);

DESCRIPTION


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

         subject       Subject that has been successfully matched
         ovector       Offset vector that pcre[16|32]_exec() used
         stringcount   Value returned by pcre[16|32]_exec()
         stringnumber  Number of the required substring
         buffer        Buffer to receive the string
         buffersize    Size of buffer

       The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was too small, 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.
