.TH PCRE_PATTERN_TO_HOST_BYTE_ORDER 3 "24 June 2012" "PCRE 8.30"
.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.nf
.B int pcre_pattern_to_host_byte_order(pcre *\fIcode\fP,
.B "     pcre_extra *\fIextra\fP, const unsigned char *\fItables\fP);"
.sp
.B int pcre16_pattern_to_host_byte_order(pcre16 *\fIcode\fP,
.B "     pcre16_extra *\fIextra\fP, const unsigned char *\fItables\fP);"
.sp
.B int pcre32_pattern_to_host_byte_order(pcre32 *\fIcode\fP,
.B "     pcre32_extra *\fIextra\fP, const unsigned char *\fItables\fP);"

.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.
.P
