PCRE_COPY_SUBSTRING(3)                      DragonFly Library Functions Manual

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.
