Function Documentation

ipv4_to_str()

static void ipv4_to_str ( const in_addr *  ipv4, char *  str  )

static

Converts IPv4-binary-address to a string.

This function is a portable alternative to inet_ntop(AF_INET).

Parameters

[in]	ipv4	IPv4-address data (byte array)
[out]	str	A buffer to store string representation of IPv4-address. It must be at least of INET_ADDRSTRLEN.

Note

The problem with inet_ntop() is that it is available starting from Windows Vista, but the minimum supported version is Windows 2000.

ipv6_to_str()

static void ipv6_to_str ( const in6_addr *  ipv6, char *  str  )

static

Converts IPv6-binary-address to a string.

This function is a portable alternative to inet_ntop(AF_INET6).

Parameters

[in]	ipv6	IPv6-address data (byte array)
[out]	str	A buffer to store string representation of IPv6-address. It must be at least of INET6_ADDRSTRLEN.

Note

The problem with inet_ntop() is that it is available starting from Windows Vista, but out the minimum supported version is Windows 2000.

str_to_ipv4()

static bool str_to_ipv4 ( const char *  str, int  str_length, in_addr *  ipv4_address  )

static

Tries to convert given string to binary IPv4-address representation.

This is a portable alternative to inet_pton(AF_INET).

Parameters

	str	String to convert.
	str_length	String length.
[out]	ipv4_address	Buffer to store IPv4-address.

Returns

Completion status.

Return values

false	Given string does not represent an IPv4-address.
true	The string has been converted successfully.

Note

The problem with inet_pton() is that it treats leading zeros in IPv4-part differently on different platforms.

str_to_ipv6()

static bool str_to_ipv6 ( const char *  str, int  str_length, in6_addr *  ipv6_address  )

static

Tries to convert given string to binary IPv6-address representation.

This is a portable alternative to inet_pton(AF_INET6).

Parameters

	str	String to convert.
	str_length	String length.
[out]	ipv6_address	Buffer to store IPv6-address.

Returns

Completion status.

Return values

false	Given string does not represent an IPv6-address.
true	The string has been converted successfully.

Note

The problem with inet_pton() is that it treats leading zeros in IPv4-part differently on different platforms.
