PCRE_PATTERN_TO_HOST_BYTE_ORDER(3) Introduction to Library Functions

NAME

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.

There is a complete description of the PCRE native API in the pcreapi
page and a description of the POSIX API in the pcreposix page.
