Detailed Description
A UDP socket.
Member Function Documentation
◆ read()
| size_t scopira::tool::udpflow::read | ( | netaddr & | actualsrc, |
| int & | actualport, | ||
| byte_t * | _buf, | ||
| size_t | _maxsize | ||
| ) |
read raw block data, returns num read in src may be netaddr::any(). actualsrc may be null, but if it isnt, it will be the actual src if the packet is bigger than the _maxsize, it will be trunced. if the packet is smaller than the _maxsize, the actual size is returned
◆ read_ready()
| bool scopira::tool::udpflow::read_ready | ( | int | msec | ) |
is anything in the input buffer, within the given time? (false==timeout) 1000msec = 1 second
◆ write()
| size_t scopira::tool::udpflow::write | ( | netaddr | dest, |
| int | destport, | ||
| const byte_t * | _buf, | ||
| size_t | _size | ||
| ) |
write a raw block of data if return 0 and not failed, then your _size > MTU remember that OS's fragmentation system pushes the perceived MTU much higher
