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]ipv4IPv4-address data (byte array)
[out]strA 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]ipv6IPv6-address data (byte array)
[out]strA 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
strString to convert.
str_lengthString length.
[out]ipv4_addressBuffer to store IPv4-address.
Returns
Completion status.
Return values
falseGiven string does not represent an IPv4-address.
trueThe string has been converted sucessfully.
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
strString to convert.
str_lengthString length.
[out]ipv6_addressBuffer to store IPv6-address.
Returns
Completion status.
Return values
falseGiven string does not represent an IPv6-address.
trueThe string has been converted sucessfully.
Note
The problem with inet_pton() is that it treats leading zeros in IPv4-part differently on different platforms.
