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);

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]_exec() used
      stringcount   Value returned by pcre[16]_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.
