|

*
|
||||
* Description:
|
||||
* recvfrom() receives messages from a local socket, and may be used to
|
||||
* receive data on a socket whether or not it is connection-oriented.
|
||||
*
|
||||
* If from is not NULL, and the underlying protocol provides the source
|
||||
* address, this source address is filled in. The argument fromlen
|
||||
* initialized to the size of the buffer associated with from, and modified
|
||||
* on return to indicate the actual size of the address stored there.
|
||||
*
|
||||
* Parameters:
|
||||
* psock A pointer to a NuttX-specific, internal socket structure
|
||||
* buf Buffer to receive data
|
||||
* len Length of buffer
|
||||
* flags Receive flags
|
||||
* from Address of source (may be NULL)
|
||||
* fromlen The length of the address structure
|
||||
*
|
||||
* Returned Value:
|
||||
* On success, returns the number of characters sent. If no data is
|
||||
* available to be received and the peer has performed an orderly shutdown,
|
||||
* recv() will return 0. Otherwise, on errors, -1 is returned, and errno
|
||||
* is set appropriately (see receivefrom for the complete list).
