NAME
       PCRE - Perl-compatible regular expressions

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);

       int pcre32_get_substring(PCRE_SPTR32 subject, int *ovector,
            int stringcount, int stringnumber,
            PCRE_SPTR32 *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|32]_exec() used
         stringcount   Value returned by pcre[16|32]_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|32]_malloc().
       The convenience function pcre[16|32]_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_NOMEM-
       ORY if sufficient 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 descrip-
       tion of the POSIX API in the pcreposix page.
