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.
