L_LTNET_API L_INT L_InetAcceptConnect(hHost, phRemote, pfnCallback, pUserData)
L_COMP hHost; |
/* handle of host computer */ |
L_COMP * phRemote; |

INETCALLBACK pfnCallback; |
/* pointer to a callback function */ |
L_VOID *pUserData; |
/* user defined callback data */ |
Accepts an incoming connection from a remote computer.
Parameter |
Description |
hHost |
Handle of the host computer which is to accept the connection |
phRemote |
Address of the variable to be updated with the handle of the remote computer to which hHost is being connected. |
pfnCallback |
Pointer to a callback function of type INETCALLBACK, for receiving messages for phRemote. Use the function pointer to your callback function as the value of this parameter. |
pUserData |
Void pointer that you can use to pass one or more additional parameters that the callback function needs. |
|
To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. |
|
If the additional parameters are not needed, you can pass NULL in this parameter. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
You must call L_InetServerInit to get a valid handle for hHost before any connections can be accepted using this function.
After this function returns, phRemote will be updated with the handle of the computer that was requesting the connection.
You can use L_InetGetHostName to see who is trying to connect to hHost, after you accept the connection, using this function. If you then wish to restrict access, you can disconnect phRemote after examining the hostname.
You must initialize the LEADTOOLS Peer-to-Peer DLL using L_InetStartUp before calling this function.
