<H2>DESCRIPTION</H2>
|
|
|
|
|
|
<P>
|
|
The <I>bytes</I> argument must point to a serialized byte stream that was
|
|
originally created by <B>pcre2_serialize_encode()</B> (though it may have been
|
|
saved on disc or elsewhere in the meantime). The function returns the number of
|
|
serialized patterns in the byte stream, or one of the following negative error
|
|
codes:
|
|
<P>
|
|
<BR> PCRE2_ERROR_BADMAGIC mismatch of id bytes in <I>bytes</I>
|
|
<BR> PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE version
|
|
<BR> PCRE2_ERROR_NULL the argument is NULL
|
|
<P>
|
|
PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
|
|
on a system with different endianness.
|
|
<P>
|
|
|
|
There is a complete description of the PCRE2 native API in the
|
|
|
|
<B>pcre2api</B>
|
|
|
|
page and a description of the serialization functions in the
|
|
|
|
<B>pcre2serialize</B>
|
|
|
|
page.
