| INT WINAPI InetRead(
|
| |
SOCKET hSocket, |
|
| |
LPBYTE lpBuffer, |
|
| |
INT cbBuffer |
|
| );
|
The InetRead function reads the specified number of bytes
from the socket and copies them into the buffer. The data may be of
any type, and is not terminated with a null-byte.
Parameters
- hSocket
- The socket handle.
- lpBuffer
- Pointer to the buffer in which the data will be copied.
- cbBuffer
- The maximum number of bytes to read and copy into the specified
buffer. This value must be greater than zero.
Return Value
If the function succeeds, the return value is the number of
bytes actually read. A return value of zero indicates that the
remote host has closed the connection and there is no more data
available to be read. If the function fails, the return value is
INET_ERROR. To get extended error information, call
InetGetLastError.
Remarks
When InetRead is called and the socket is in non-blocking
mode, it is possible that the function will fail because there is
no available data to read at that time. This should not be
considered a fatal error. Instead, the application should simply
wait to receive the next asynchronous notification that data is
available.
Requirements
Client: Requires Windows 7, Windows Vista or Windows
XP.
Server: Requires Windows Server 2008 or Windows Server
2003.
Header: Include cswsock7.h.
Library: Use cswskav7.lib.
