Its arguments are: 32<pre> 33 <i>codes</i> pointer to a vector in which to build the list 34 <i>number_of_codes</i> number of slots in the vector 35 <i>bytes</i> the serialized byte stream 36 <i>gcontext</i> pointer to a general context or NULL 37</pre> 38The <i>bytes</i> argument must point to a block of data that was originally 39created by <b>pcre2_serialize_encode()</b>, though it may have been saved on 40disc or elsewhere in the meantime. If there are more codes in the serialized 41data than slots in the list, only those compiled patterns that will fit are 42decoded. The yield of the function is the number of decoded patterns, or one of 43the following negative error codes: 44<pre> 45 PCRE2_ERROR_BADDATA <i>number_of_codes</i> is zero or less 46 PCRE2_ERROR_BADMAGIC mismatch of id bytes in <i>bytes</i> 47 PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE version 48 PCRE2_ERROR_MEMORY memory allocation failed 49 PCRE2_ERROR_NULL <i>codes</i> or <i>bytes</i> is NULL 50</pre> 51PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled 52on a system with different endianness. 53</P> 54<P> 55There is a complete description of the PCRE2 native API in the 56<a href="pcre2api.html"><b>pcre2api</b></a> 57page and a description of the POSIX API in the 58<a href="pcre2posix.html"><b>pcre2posix</b></a> 59page. 60<p> 61Return to the <a href="index.html">PCRE2 index page</a>. 62</p> 63
