   34 DESCRIPTION
   35 </b><br>
   36 <P>
   37 This function ensures that the bytes in 2-byte and 4-byte values in a compiled
   38 pattern are in the correct order for the current host. It is useful when a
   39 pattern that has been compiled on one host is transferred to another that might
   40 have different endianness. The arguments are:
   41 <pre>
   42   <i>code</i>         A compiled regular expression
   43   <i>extra</i>        Points to an associated <b>pcre[16|32]_extra</b> structure,
   44                  or is NULL
   45   <i>tables</i>       Pointer to character tables, or NULL to
   46                  set the built-in default
   47 </pre>
   48 The result is 0 for success, a negative PCRE_ERROR_xxx value otherwise.
