Syntax
int SyncRecvfromAddrSc(
SOCKET sock,
void *pvRecvBuf,
unsigned short u16BufLen,
unsigned long u32Timeoutmsec,
unsigned short *u16RemainingLen,
struct sockaddr_in *pstrRemoteAddr
);
Parameters
- sock
- [in] Socket descriptor
- pvRecvBuf
- [out] Specify the receive buffer.
- u16BufLen
- [in] Specify the size (bytes) of the receive buffer.
- u32Timeoutmsec
-
[in] Specify the timeout (msec).
If you specify 0 or 4294967295 (0xFFFFFFFF), it will not time out. - u16RemainingLen
- [out] The remaining size (in bytes) of the current receive operation.
- pstrRemoteAddr
- [out]A pointer to the sockaddr_in structure.
Return value
The following values will be returned.| Value | Description |
|---|---|
| Positive number | Receive size. |
| SOCK_ERR_TIMEOUT | If no data was received during the timeout. |
| SOCK_ERROR | Socket error Close the socket and recreate it. |
| SOCK_CLOSE | Remote disconnect Close the socket and recreate it. |
| SOCK_RECV_ERROR | Receive error The receive size has exceeded the buffer size. Please adjust the buffer size to an appropriate size. |
| M2M_ERR_SLEEP_FAIL | Initialize with SysWLANInit function. |
| Other than the above | Failed |
Remarks
Since TH15J09, the API name has been changed from SyncRecvfromSc to SyncRecvfromAddrSc, and pstrRemoteAddr has been added as the 6th argument.Specify NULL if you do not use pstrRemoteAddr
SyncRecvfromSc can be used as before, but we recommend migrating to SyncRecvfromAddrSc.
