Function recv [src]
Prototype
pub fn recv(sock: socket_t, buf: []u8, flags: u32) RecvFromError!usize Parameters
sock: socket_tbuf: []u8flags: u32 Possible Errors
A remote host refused to allow the network connection, typically because it is not running the requested service.
The UDP message was too big for the buffer and part of it has been discarded
The network subsystem has failed.
The socket has not been bound.
The socket is not connected (connection-oriented sockets only).
Could not allocate kernel memory.
The Operating System returned an undocumented error code.
This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.
When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.
The socket is marked nonblocking and the requested operation would block, and there is no global event loop configured.
