DESCRIPTION
|
|
</b><br>
|
|
<P>
|
|
This function decodes a serialized set of compiled patterns back into a list of
|
|
individual patterns. Its arguments are:
|
|
<pre>
|
|
<i>codes</i> pointer to a vector in which to build the list
|
|
<i>number_of_codes</i> number of slots in the vector
|
|
<i>bytes</i> the serialized byte stream
|
|
<i>gcontext</i> pointer to a general context or NULL
|
|
</pre>
|
|
The <i>bytes</i> argument must point to a block of data that was originally
|
|
created by <b>pcre2_serialize_encode()</b>, though it may have been saved on
|
|
disc or elsewhere in the meantime. If there are more codes in the serialized
|
|
data than slots in the list, only those compiled patterns that will fit are
|
|
decoded. The yield of the function is the number of decoded patterns, or one of
|
|
the following negative error codes:
|
|
<pre>
|
|
PCRE2_ERROR_BADDATA <i>number_of_codes</i> is zero or less
|
|
PCRE2_ERROR_BADMAGIC mismatch of id bytes in <i>bytes</i>
|
|
PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE version
|
|
PCRE2_ERROR_MEMORY memory allocation failed
|
|
PCRE2_ERROR_NULL <i>codes</i> or <i>bytes</i> is NULL
|
|
</pre>
|
|
PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
|
|
on a system with different endianness.
