Socket stream functions are used for socket stream operations.
◆ rtxStreamSocketAttach()
EXTERNRT int rtxStreamSocketAttach |
( |
OSCTXT * |
pctxt, |
|
|
OSRTSOCKET |
socket, |
|
|
OSUINT16 |
flags |
|
) |
| |
Attaches the existing socket handle to the stream.
The socket should be already opened and connected. The 'flags' parameter specifies the access mode for the stream - input or output.
- Parameters
-
pctxt | Pointer to a context structure variable that has been initialized for stream operations. |
socket | The socket handle created by rtxSocketCreate . |
flags | Specifies the access mode for the stream:
- OSRTSTRMF_INPUT = input (reading) stream;
- OSRTSTRMF_OUTPUT = output (writing) stream.
|
- Returns
- Completion status of operation: 0 = success, negative return value is error.
◆ rtxStreamSocketClose()
EXTERNRT int rtxStreamSocketClose |
( |
OSCTXT * |
pctxt | ) |
|
This function closes a socket stream.
- Parameters
-
pctxt | Pointer to a context structure variable that has been initialized for stream operations. |
- Returns
- Completion status of operation: 0 = success, negative return value is error.
◆ rtxStreamSocketCreateWriter()
EXTERNRT int rtxStreamSocketCreateWriter |
( |
OSCTXT * |
pctxt, |
|
|
const char * |
host, |
|
|
int |
port |
|
) |
| |
This function opens a socket stream for writing.
- Parameters
-
pctxt | Pointer to a context structure variable that has been initialized for stream operations. |
host | Name of host or IP address to which to connect. |
port | Port number to which to connect. |
- Returns
- Completion status of operation: 0 = success, negative return value is error.
◆ rtxStreamSocketSetOwnership()
EXTERNRT int rtxStreamSocketSetOwnership |
( |
OSCTXT * |
pctxt, |
|
|
OSBOOL |
ownSocket |
|
) |
| |
This function transfers ownership of the socket to or from the stream instance.
The socket will be closed and deleted when the stream is closed or goes out of scope. By default stream socket owns the socket.
- Parameters
-
pctxt | Pointer to a context structure variable that has been initialized for stream operations. |
ownSocket | Boolean value. |
- Returns
- Completion status of operation: 0 = success, negative return value is error.
◆ rtxStreamSocketSetReadTimeout()
EXTERNRT int rtxStreamSocketSetReadTimeout |
( |
OSCTXT * |
pctxt, |
|
|
OSUINT32 |
nsecs |
|
) |
| |
This function sets the read timeout value to the given number of seconds.
Any read operation attempted on the stream will timeout after this period of time if no data is received.
- Parameters
-
pctxt | Pointer to a context structure variable that has been initialized for stream operations. |
nsecs | Number of seconds to wait before timing out. |
- Returns
- Completion status of operation: 0 = success, negative return value is error.
