function fprecv(s: cint; buf: pointer; len: size_t; flags: cint)
: ssize_t;
Description
fpRecv reads at most len bytes from socket S into address buf. The socket must be in a connected state. Flags can be one of the following:
- 1
- Process out-of band data.
- 4
- Bypass routing, use a direct interface.
- ??
- Wait for full request or report an error.
The functions returns the number of bytes actually read from the socket, or -1 if a detectable error occurred.
Errors
Errors are reported in SocketError, and include the following:
- ESockEBADF
- The socket descriptor is invalid.
- ESockENOTCONN
- The socket isn't connected.
- ESockENOTSOCK
- The descriptor is not a socket.
- ESockEFAULT

- ESockEMSGSIZE
- The message cannot be sent atomically.
