/**

Receive data from a network connection.
|
|
|
|
The recv routine waits for receive data from a remote network
|
|
connection. This routine is typically used for SOCK_STREAM
|
|
because it waits for receive data from the target system specified
|
|
in the ::connect call.

|
|
|
@param [in] s Socket file descriptor returned from ::socket.
|
|
|
|
@param [in] buffer Address of a buffer to receive the data.
|
|
|
|
@param [in] length Length of the buffer in bytes.
|
|
|
|
@param [in] flags Message control flags
|
|
|
|
@return This routine returns the number of valid bytes in the buffer,
|
|
zero if no data was received, and -1 when an error occurs.
|
|
In the case of an error, ::errno contains more details.
