.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.
