.SH DESCRIPTION
.rs
.sp
This function ensures that the bytes in 2-byte and 4-byte values in a compiled
pattern are in the correct order for the current host. It is useful when a
pattern that has been compiled on one host is transferred to another that might
have different endianness. The arguments are:
.sp
  \fIcode\fP         A compiled regular expression
  \fIextra\fP        Points to an associated \fBpcre[16|32]_extra\fP structure,
                 or is NULL
  \fItables\fP       Pointer to character tables, or NULL to
                 set the built-in default
.sp
The result is 0 for success, a negative PCRE_ERROR_xxx value otherwise.
