This is a convenience function for extracting a captured substring by name. The |
| 44 |
|
|
arguments are: |
| 45 |
|
|
<pre> |
| 46 |
|
|
<i>code</i> Compiled pattern |
| 47 |
|
|
<i>subject</i> Subject that has been successfully matched |
| 48 |
ph10 |
1194 |
<i>ovector</i> Offset vector that <b>pcre[16|32]_exec()</b> used |
| 49 |
|
|
<i>stringcount</i> Value returned by <b>pcre[16|32]_exec()</b> |
| 50 |
nigel |
63 |
<i>stringname</i> Name of the required substring |
| 51 |
|
|
<i>stringptr</i> Where to put the string pointer |
| 52 |
nigel |
75 |
</pre> |
| 53 |
|
|
The memory in which the substring is placed is obtained by calling |
| 54 |
ph10 |
1194 |
<b>pcre[16|32]_malloc()</b>. The convenience function |
| 55 |
|
|
<b>pcre[16|32]_free_substring()</b> can be used to free it when it is no longer |
| 56 |
ph10 |
869 |
needed. The yield of the function is the length of the extracted substring, |
| 57 |
|
|
PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or |
| 58 |
|
|
PCRE_ERROR_NOSUBSTRING if the string name is invalid. |
