PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
int pcre_pattern_to_host_byte_order(pcre *code,
pcre_extra *extra, const unsigned char *tables);
int pcre16_pattern_to_host_byte_order(pcre16 *code,
pcre16_extra *extra, const unsigned char *tables);
int pcre32_pattern_to_host_byte_order(pcre32 *code,
pcre32_extra *extra, const unsigned char *tables);
DESCRIPTION
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:
code A compiled regular expression
extra Points to an associated pcre[16|32]_extra structure,
or is NULL
tables Pointer to character tables, or NULL to
set the built-in default
The result is 0 for success, a negative PCRE_ERROR_xxx value otherwise.
