| 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. |
