.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.
