DESCRIPTION

<P>
|
||
|
|
This is a convenience function for extracting a captured substring by number into
|
||
|
|
newly acquired memory. The arguments are:
|
||
|
|
<pre>
|
||
|
|
<i>match_data</i> The match data for the match
|
||
|
|
<i>number</i> Number of the required substring
|
||
|
|
<i>bufferptr</i> Where to put the string pointer
|
||
|
|
<i>bufflen</i> Where to put the string length
|
||
|
|
</pre>
|
||
|
|
The memory in which the substring is placed is obtained by calling the same
|
||
|
|
memory allocation function that was used for the match data block. The
|
||
|
|
convenience function <b>pcre2_substring_free()</b> can be used to free it when
|
||
|
|
it is no longer needed. The yield of the function is zero for success,
|
||
|
|
PCRE2_ERROR_NOMEMORY if sufficient memory could not be obtained, or
|
||
|
|
PCRE2_ERROR_NOSUBSTRING if the string number is invalid.
