pub unsafe fn getsockname(
sockfd: int,
addr: *mut sockaddr,
addrlen: *mut socklen_t,
) -> Result<int>Expand description
Get the address that a socket is bound to.
Socket addresses have varying lengths depending on address family. Callers
should pass a buffer of the appropriate size for the socket’s address
family and indicate that buffer size in addrlen.
Updates the value at addrlen to reflect the number of bytes actually
needed, which might be longer than the given addrlen if the given buffer
is too short for the address, in which case the value written to addr is
truncated to fit.
