Overview

Platform-neutral BSD-modeled network socket implementation.

#include "lwpa_socket.h"

This module attempts to abstract the network socket interface from various platforms into one platform-neutral interface. The functions and flags are modeled after the BSD sockets interface. UNIX Network Programming: The Sockets Networking API by Stevens, Fenner, and Rudoff is highly recommended reading for those unfamiliar with this interface.

Typedef Documentation

◆ lwpa_socket_t

typedef UNDEFINED lwpa_socket_t

A socket handle.

Typedefed to the system's socket identifier.

◆ LwpaAddrinfo

typedef struct LwpaAddrinfo LwpaAddrinfo

A structure containing name and address information about an internet host.

Returned by lwpa_getaddrinfo().

Function Documentation

◆ lwpa_accept()

lwpa_error_t lwpa_accept	(	lwpa_socket_t	id,
		LwpaSockaddr *	address,
		lwpa_socket_t *	conn_sock
	)

Accept a connection on a socket.

Refer to your favorite accept() man page for more information.

Differences from POSIX: addrlen parameter is omitted because there is only one lwpa sockaddr type. Connected socket is returned in an output parameter rather than the return value.

Parameters

[in]	id	Listening socket on which to accept a new connection.
[out]	address	Remote address from which the connection was accepted.
[out]	conn_sock	Filled in on success with handle to connected socket.

Returns: LWPA_OK (success) or lwpa_error_t code from system (failure).

◆ lwpa_bind()

lwpa_error_t lwpa_bind	(	lwpa_socket_t	id,
		const LwpaSockaddr *	address
	)

Bind a name to a socket.

Refer to your favorite bind() man page for more information.

Differences from POSIX: addrlen parameter is omitted because there is only one lwpa sockaddr type.

Parameters

[in]	id	Socket to which to bind an address (traditionally called a 'name').
[in]	address	Address to assign to the socket.

Returns: LWPA_OK (success) or lwpa_error_t code from system (error occurred).

◆ lwpa_close()

lwpa_error_t lwpa_close ( lwpa_socket_t id )

Close a socket.

Refer to your favorite close() man page for more information.

On UNIX-like systems, note that this may also successfully close descriptors that don't refer to sockets; however, for portability it should only be used on identifiers that were returned from an lwpa_* function.

Parameters

[in] id Socket to close.

Returns: LWPA_OK (success) or lwpa_error_t code from system (error occurred).

◆ lwpa_connect()

lwpa_error_t lwpa_connect	(	lwpa_socket_t	id,
		const LwpaSockaddr *	address
	)

Initiate a connection on a socket.

Refer to your favorite connect() man page for more information.

Differences from POSIX: addrlen parameter is omitted because there is only one lwpa sockaddr type.

Parameters

[in]	id	Socket to connect.
[in]	address	Address to which to connect.

Returns: LWPA_OK (success) or lwpa_error_t code from system (error occurred).

◆ lwpa_freeaddrinfo()

void lwpa_freeaddrinfo ( LwpaAddrinfo * ai )

Free an addrinfo list returned by lwpa_getaddrinfo().

Most platforms allocate memory when getaddrinfo() is called. This must always be called after any call to lwpa_getaddrinfo() to free that memory. It can be called with any of the LwpaAddrinfo instances in the list, and the whole list will be freed. See the example usage in the description of lwpa_getaddrinfo().

Parameters

[in] ai Pointer to lwpa_addrinfo struct for which to free the platform memory.

◆ lwpa_getaddrinfo()

lwpa_error_t lwpa_getaddrinfo	(	const char *	hostname,
		const char *	service,
		const LwpaAddrinfo *	hints,
		LwpaAddrinfo *	result
	)

Get address information for a named internet host and/or service.

Refer to your favorite getaddrinfo() man page for more information. One difference between this and the POSIX function is the way that multiple addresses are iterated. lwpa uses the lwpa_nextaddr() function instead of a next pointer to iterate over multiple addresses. For example:

LwpaAddrinfo info;
if (0 == lwpa_getaddrinfo("www.google.com", "http", NULL, &info))
{
  do
  {
    char inet_str[LWPA_INET6_ADDRSTRLEN];
    if (LWPA_OK == lwpa_inet_ntop(&info.ai_addr.ip, inet_str,
                                  LWPA_INET6_ADDRSTRLEN))
    {
      printf("Address: %s\n", inet_str);
    }
    else
      printf("Address conversion error!\n");
 
  } while (lwpa_nextaddr(&info));
 
  lwpa_freeaddrinfo(&info);
}

On an internet-connected machine with DNS resolution capability, the above code should print something like:

Address: 172.217.4.196
Address: 172.217.4.196
Address: 2607:f8b0:4009:806::2004
Address: 2607:f8b0:4009:806::2004

Parameters

[in]	hostname	Either a string-represented numerical network address or a network hostname to resolve.
[in]	service	Either a string-represented numerical port number or a service name.
[in]	hints	Structure containing hints restricting the address types that can be returned.
[out]	result	On success, filled in with the first address result.

Returns: LWPA_OK (success) or lwpa_error_t code from system (an error occurred).

◆ lwpa_getpeername()

lwpa_error_t lwpa_getpeername	(	lwpa_socket_t	id,
		LwpaSockaddr *	address
	)

Get the name of the connected peer socket.

Refer to your favorite getpeername() man page for more information.

Differences from POSIX: addrlen parameter is omitted because there is only one lwpa sockaddr type.

[in]	id	Connected socket for which to get the peer address.
[in]	address	Filled in with peer address on success.

Returns: LWPA_OK (success) or lwpa_error_t code from system (error occurred).

lwpa_error_t lwpa_getsockname	(	lwpa_socket_t	id,
		LwpaSockaddr *	address
	)

Get socket name.

Refer to your favorite getsockname() man page for more information.

Differences from POSIX: addrlen parameter is omitted because there is only one lwpa sockaddr type.

Parameters

[in]	id	Connected socket for which to get the bound address.
[in]	address	Filled in with bound address on success.

Returns: LWPA_OK (success) or lwpa_error_t code from system (error occurred).

		int	option_name,
		void *	option_value,
		size_t *	option_len
	)

Get an option value for a socket.

Refer to your favorite getsockopt() man page for more information.

Differences from POSIX: Some overlapping option values are consolidated and some legacy option values are not included. Some value types are different; see the documentation of each possible option value.

Parameters

[in]	id	Socket for which to get the option value.
[in]	level	Protocol level of the option for which to get the value.

		size_t	size
	)

Convert IPv4 and IPv6 addresses from binary to text form.

Refer to your favorite inet_ntop() man page for more information.

Differences from POSIX: af parameter is omitted because that information is contained in the struct lwpa_ip.

Parameters

[in]	src	Address to convert to string form.
[out]	dest	Filled in on success with the string-represented address.
[in]	size	Size in bytes of dest buf.

Refer to your favorite inet_pton() man page for more information.

Differences from POSIX: lwpa_iptype_t used instead of AF_* value, since this function is only used for IP addresses.

Parameters

[in]	type	Type of string-represented IP address pointed to by src.
[in]	src	Character string containing a string-represented IP address.
[out]	dest	Filled in on success with the address.

◆ lwpa_nextaddr()

bool lwpa_nextaddr ( LwpaAddrinfo * ai )

Get the next address from the list returned by lwpa_getaddrinfo().

Most platforms allocate and return a linked list of address info structs in their getaddrinfo() implementation. To avoid further memory allocation in the abstraction layer, this non-POSIX-like way to iterate through the addrinfo structs is provided. To get all of the addresses returned from a lwpa_getaddrinfo() call, keep calling this on the result struct until it returns false.

Parameters

[in,out] ai Pointer to last lwpa_addrinfo struct, filled in with values of the next address.

Returns: true (next address was filled in) or false (no more addresses or error).

◆ lwpa_poll()

int lwpa_poll	(	LwpaPollfd *	fds,
		size_t	nfds,
		int	timeout_ms
	)

Wait for some event on a set of sockets.

Refer to your favorite poll() man page for more information.

On UNIX-like systems, note that this may also work for descriptors that don't refer to sockets; however, for portability it should only be used on identifiers that were returned from an lwpa_* function.

Parameters

[in,out]	fds	Set of socket descriptors to be monitored.
[in]	nfds	Number of LwpaPollfd structs in the fds array.
[in]	timeout_ms	How long to wait for an event, in milliseconds. Use LWPA_WAIT_FOREVER to wait indefinitely.
