PCRE_PATTERN_TO_HOST_BYTE_ORDER

Section: C Library Functions (3)
Updated: 24 June 2012
Index Return to Main Contents
 

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.
