Macro Definition Documentation

◆ closesocket

#define closesocket ( socket )

Value:

close(socket)

Function Documentation

◆ ws_cleanup_sockets()

WS_DLL_PUBLIC void ws_cleanup_sockets ( void )

Cleans up the socket subsystem.

Performs any necessary platform-specific cleanup for socket operations.

◆ ws_init_sockets()

WS_DLL_PUBLIC char * ws_init_sockets ( void )

Initializes the socket subsystem.

Performs any necessary platform-specific setup for socket operations.

Returns: NULL on success, or a g_malloc()ed error message string on failure. The caller is responsible for freeing the returned string.

◆ ws_socket_ptoa()

WS_DLL_PUBLIC int ws_socket_ptoa	(	struct sockaddr_storage *	dst,
		const char *	src,
		uint16_t	def_port )

Converts a string representation of an IP address and port into a sockaddr.

Converts a string of the form ipv4_address:port or [ipv6_address]:port into a sockaddr_storage structure. If the port is omitted, def_port is used.

Parameters

dst	Pointer to a sockaddr_storage structure to receive the parsed address.
src	The input string containing the address and optional port.
def_port	The default port to use if none is specified (in host byte order).

Returns: 0 on success, or -1 on failure (e.g., invalid format or address).

◆ ws_verify_peercred()

WS_DLL_PUBLIC bool ws_verify_peercred ( int sock )

Verify the credentials of the peer connected to a Unix domain socket.

Verifies that the UID of the peer process that is connected to a Unix domain socket is the same as the effective UID of the current process, if possible.
