 The function `mg_read()` receives data over an existing connection. The data is handled as binary and is stored in a buffer whose address has been provided as a parameter. The function returns the number of read bytes when successful, the value **0** when the connection has been closed by peer and a negative value when no more data could be read from the connection.
 
+### Example

+```
+#define RECV_BUF_SIZE 1 << 20
+
+size_t read_data(struct mg_connection* conn,
+                        uint8_t* buff,

+  while (read_len < buff_len) {
+    size_t sz_to_read = std::min<size_t>(RECV_BUF_SIZE, buff_len - read_len);
+    int this_read = mg_read(conn, buff + read_len, sz_to_read);
