inet_addr()

uint32_t inet_addr

(

const char *

name

)

Converts a number-and-dot notation internet address to network byte order form.

Parameters

name	is the text representation.

Returns

the 32-bit address in ntwork byte order, or -1 if there is an error.

Converts a number-and-dot notation internet address to network byte order form.

Parameters

name	string containing dotted decimal representation

Returns

binary address representation

Definition at line 999 of file FreeRTOSTCPSocket.cxx.

inet_aton()

int inet_aton	(	const char *	name,
		struct in_addr *	addr
	)

Converts a number-and-dot notation internet address to binary form.

Parameters

name	standard argument
addr	standard argument

Returns

error code

inet_ntoa()

char * inet_ntoa

(

struct in_addr

addr

)

Converts an address to textual representation.

Not reentrant.

Parameters

addr	is the address.

Returns

the textual form of the address (statically allocated buffer).

Converts an address to textual representation.

Parameters

addr	an in_addr structure containing the IP address

Returns

returns a string in dotted decimal representation

Definition at line 987 of file FreeRTOSTCPSocket.cxx.

inet_ntop()

const char * inet_ntop	(	int	af,
		const void *	src,
		char *	dst,
		socklen_t	size
	)

Convert the network address in src to a character string in src.

Parameters

af	address family, AF_INET or AF_INET6
src	source address in network byte order
dst	resulting address string
size	max number characters allowed for the result

Returns

on success non-null pointer to dst, else NULL with errno set on error
