Prototype

          void  NetASCII_IPv6_to_Str(NET_IPv6_ADDR  *p_addr_ip,
                                     CPU_CHAR       *p_addr_ip_ascii,
                                     CPU_BOOLEAN     hex_lower_case,
                                     CPU_BOOLEAN     lead_zeros,
                                     NET_ERR        *p_err);

Arguments

p_addr_ip

Pointer to IPv6 address.

p_addr_ip_ascii

Pointer to a memory buffer of size greater than or equal to NET_ASCII_LEN_MAX_ADDR_IPv6 bytes to receive the IPv6 address string.

hex_lower_case

Select if IPv6 address hexadecimal ASCII representation will be in lower or in upper case. 

lead_zeros

Select formatting the IPv6 address string with leading zeros (‘0’) prior to the first non-zero digit in each IPv6 address hexadecimal section of 2 bytes.

DEF_NO

Do not prepend leading zeros to each IPv6 address 16 bits sections.

DEF_YES

Prepend leading zeros to each IPv6 address 16 bits sections.

p_err

Pointer to variable that will receive the return error code from this function:

NET_ASCII_ERR_NONE
NET_ERR_FAULT_NULL_PTR
NET_ASCII_ERR_INVALID_CHAR_LEN

Returned Value

None.

Required Configuration

Available only if IPv6 is enabled, see IPv6 Layer Configuration

Notes / Warnings

IPv6 addresses are formed of 128 bits. They are represented as a sequence of 8 series of 16 bits, each represented in a hexadecimal notation and divided by a common. Example : FE80:1111:1111:1111:1111:1111:1111:1111. 

Please refer to RFC 4291 for more details on IPv6 addressing.
