       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre32_utf32_to_host_byte_order(PCRE_UCHAR32 *output,
            PCRE_SPTR32 input, int length, int *host_byte_order,
            int keep_boms);

DESCRIPTION

       This  function,  which  exists only in the 32-bit library, converts a UTF-32 string to the
       correct order for the current host, taking account of any byte order marks  (BOMs)  within
       the string. Its arguments are:

         output           pointer to output buffer, may be the same as input
         input            pointer to input buffer
         length           number of 32-bit units in the input, or negative for
                            a zero-terminated string
         host_byte_order  a NULL value or a non-zero value pointed to means
                            start in host byte order
         keep_boms        if non-zero, BOMs are copied to the output string

       The  result  of  the function is the number of 32-bit units placed into the output buffer,
       including the zero terminator if the string was zero-terminated.

       If host_byte_order is not NULL, it is set to indicate the byte order that  is  current  at
       the end of the string.

       description of the POSIX API in the pcreposix page.
