| 16 | .SH DESCRIPTION |
| 17 | .rs |
| 18 | .sp |
| 19 | This is a convenience function for extracting a captured substring into a given |
| 20 | buffer. The 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 | \fIbuffer\fP Buffer to receive the string |
| 27 | \fIbuffersize\fP Size of buffer |
| 28 | .sp |
| 29 | The yield is the length of the string, PCRE_ERROR_NOMEMORY if the buffer was |
| 30 | too small, or PCRE_ERROR_NOSUBSTRING if the string number is invalid. |
