SYNOPSIS top


       #include <pcre.h>

       int pcre_copy_named_substring(const pcre *code,
            const char *subject, int *ovector,
            int stringcount, const char *stringname,
            char *buffer, int buffersize);

       int pcre16_copy_named_substring(const pcre16 *code,
            PCRE_SPTR16 subject, int *ovector,
            int stringcount, PCRE_SPTR16 stringname,
            PCRE_UCHAR16 *buffer, int buffersize);

       int pcre32_copy_named_substring(const pcre32 *code,
            PCRE_SPTR32 subject, int *ovector,
            int stringcount, PCRE_SPTR32 stringname,
            PCRE_UCHAR32 *buffer, int buffersize);

DESCRIPTION top


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

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

       The yield is the length of the substring, PCRE_ERROR_NOMEMORY if
       the buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string
       name 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.
