Detailed Description

Socket message flags

The following flags can be used with the recv(), recvfrom(), send(), and sendto() functions as the flags parameter.

Note that not all of these are currently supported, but they are listed for completeness. Those that are unsupported have (U) at the end of their description. Also, for the time being, the supported flags are only supported for TCP.
