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.

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.
