| int64_t eq::net::FDConnection::read | ( | void * | buffer, | |
| const uint64_t | bytes | |||
| ) | [virtual] |
Read data from the connection.
Note the the a return value of 0 is not an error condition, it means that no data was pending on a non-blocking connection.
- Parameters:
-
buffer the buffer for saving the message. bytes the number of bytes to read.
- Returns:
- the number of bytes read, or -1 upon error.
Implements eq::net::Connection.

| int64_t eq::net::FDConnection::write | ( | const void * | buffer, | |
| const uint64_t | bytes | |||
| ) | const [virtual] |
Write data to the connection.
- Parameters:
-
buffer the buffer containing the message. bytes the number of bytes to write.
- Returns:
- the number of bytes written, or -1 upon error.
