Receive a message from a socket
sock_recv (
sock: i32The file descriptor of the socket to receive fromri_data: i32A list of scatter/gather vectors to which the received data will be storedri_data_len: i32The length of the scatter/gather vector listri_flags: i32Message flagsro_data_len: i32A pointer to store the number of bytes readro_flags: i32A pointer to store the message flags
) => The sock_recv()
function is used to receive a message from a socket. It is similar to the recv
function in POSIX, but it also supports reading the data into multiple buffers in the manner of readv
.
The function receives data from the socket and stores it in the provided scatter/gather vectors. The number of bytes stored in ri_data
and the message flags are returned.
Notes
- The
sock_recv()
function receives a message from a socket and stores it in the provided scatter/gather vectors. - The function supports reading the data into multiple buffers.
- The
ri_data
parameter represents a list of scatter/gather vectors, where each vector contains a buffer and its length. - The
ri_data_len
parameter specifies the length of the scatter/gather vector list. - The received data is stored in the buffers specified by the scatter/gather vectors.
- The number of bytes read from the socket is stored in
ro_data_len
. - The message flags are stored in
ro_flags
. - The specific behavior of the
sock_recv()
function may vary depending on the runtime environment and underlying networking implementation.
