    EAGAIN,
    EBADF,

    EISDIR,
    ENOMEM,
    OpCode,
}

Variants

EAGAIN

Non-blocking I/O has been selected using O_NONBLOCK and the read would block.

EBADF

fd is not a valid file descriptor or is not open for reading

EFAULT

buf is outside your accessible address space

EINTR

The call was interrupted by a signal before any data was read

EINVAL

fd is attached to an object which is unsuitable for reading; or the file was opened with the O_DIRECT flag, and either the address specified in buf, the value specified in count, or the current file offset is not suitably aligned

EIO

I/O error. This will happen for example when the process is in a background process group, tries to read from its controlling tty, and either it is ignoring or blocking SIGTTIN or its process group is orphaned. It may also occur when there is a low-level I/O error while reading from a disk or tape.

EISDIR

fd refers to a directory.

ENOMEM

Insufficient memory is available

OpCode

Invalid OpCode. According to RFC-6455: “If an unknown opcode is received, the receiving endpoint MUST Fail the WebSocket Connection”
