2N/A.SH NAME

2N/Aip6 \- IP V6 address support

2N/A.SH SYNOPSIS

2N/A.EX

2N/A#include <ip6.h>

2N/A

2N/Achar* fmtip6(unsigned char* addr, int bits);

2N/Aint strtoip6(const char* str, char** end, unsigned char* addr, unsigned char* bits);

2N/A.SH DESCRIPTION

2N/A.L fmtip6()

2N/Aformats the IPV6 address

2N/A.L addr

2N/Awith optional prefix bits

2N/A.L bits

(0 if not a prefix) into a thread-specific 0-terminated temporary buffer and returns a pointer

to the formatted value.

.PP

.L strtoip6()

converts a formatted IPV6 address from the 0-terminated string

.L str

into a host order IPV6 address in

.L addr

which must be a buffer of at least

.L IP6ADDR

bytes.

If

.L bits

is not 0 then an optional

.BI / bits

(prefix size in bits) is parsed and

.L *bits

is set to the number of prefix bits.

If

.L end

is not 0 then

.L *end

will point to the first unparsed character in

.L str

on return.

0 is returned on success, -1 on failure.
