+### `uv.pipe_bind2(pipe, name, [flags])`
+
+> method form `pipe:bind2(name, [flags])`
+
+**Parameters:**
+- `pipe`: `uv_pipe_t userdata`
+- `name`: `string`
+- `flags`: `integer`(default: 0) 
+
+Bind the pipe to a file path (Unix) or a name (Windows).
+
+`Flags` must be zero or `uv.constants.PIPE_NO_TRUNCATE`. Returns `EINVAL` for unsupported flags without performing the bind operation.
+
+Supports Linux abstract namespace sockets. namelen must include the leading '\0' byte but not the trailing nul byte.
+
+**Returns:** `0` or `fail`
+
+**Note**:
+1. Paths on Unix get truncated to sizeof(sockaddr_un.sun_path) bytes,
+typically between 92 and 108 bytes.
+2. New in version 1.46.0.
+
+### `uv.pipe_connect2(pipe, name, [flags], [callback])`
+
+> method form `pipe:connect2(name, [flags], [callback])`
+
+**Parameters:**
+- `pipe`: `uv_pipe_t userdata`
+- `name`: `string`
+- `flags`: `integer`(default: 0)
+- `callback`: `callable` or `nil`
+ - `err`: `nil` or `string`
+
+Connect to the Unix domain socket or the named pipe.
+
+`Flags` must be zero or `uv.constants.PIPE_NO_TRUNCATE`. Returns `EINVAL` for unsupported flags without performing the bind operation.
+
+Supports Linux abstract namespace sockets. namelen must include the leading nul byte but not the trailing nul byte.
+
+**Returns:** `uv_connect_t userdata` or `fail`
+
+**Note**:
+1. Paths on Unix get truncated to sizeof(sockaddr_un.sun_path) bytes,
+typically between 92 and 108 bytes.
+2. New in version 1.46.0.
