pcre32_pattern_to_host_byte_order: Perl-compatible regular expressions

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.
