The
WSABUF structure enables the creation or manipulation of a data buffer.
Syntax
typedef struct __WSABUF {
u_long len;
char FAR *buf;
}WSABUF, *LPWSABUF;
Members
- len
Length of the buffer, in bytes.
- buf
Pointer to the buffer.
Example Code
The following example demonstrates the use of the WSABUF structure.
WSABUF DataBuf;
char SendBuf[1024] = "Test data to send.";
int BufLen = 1024;
//...
DataBuf.len = BufLen;
DataBuf.buf = SendBuf;
//...
WSASendTo(SendSocket,
&DataBuf,
1,
&BytesSent,
Flags,
(SOCKADDR*) &RecvAddr,
RecvAddrSize,
&Overlapped,
NULL);
