                     16: .SH DESCRIPTION
                     17: .rs
                     18: .sp
                     19: This is a convenience function for extracting a captured substring. The
                     20: arguments are:
                     21: .sp
                     22:   \fIsubject\fP       Subject that has been successfully matched
                     23:   \fIovector\fP       Offset vector that \fBpcre_exec()\fP used
                     24:   \fIstringcount\fP   Value returned by \fBpcre_exec()\fP
                     25:   \fIstringnumber\fP  Number of the required substring
                     26:   \fIstringptr\fP     Where to put the string pointer
                     27: .sp
                     28: The memory in which the substring is placed is obtained by calling
                     29: \fBpcre_malloc()\fP. The convenience function \fBpcre_free_substring()\fP can
                     30: be used to free it when it is no longer needed. The yield of the function is
                     31: the length of the substring, PCRE_ERROR_NOMEMORY if sufficient memory could not
                     32: be obtained, or PCRE_ERROR_NOSUBSTRING if the string number is invalid.
                     33: .P
                     34: There is a complete description of the PCRE native API in the
                     35: .\" HREF
