Синопсис (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);
Описание (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.
