int ADM_receive_sk(char *skName, char *holdRecPtr, int *readLen, char *fromIP);
Parameters
skName Name of the socket that has been initialized and used to receive data.
holdRecPtr Pointer to a buffer to hold data that will be received by the API.
readLen Length of data received by the API.
fromIP Pointer to character array which in turn return with client IP.
Description
This function receives socket after ADM_open_sk is used. skName must be a
valid name that has been initialized with ADM_init_socket.
Return Value
SK_SUCCESS Socket is successfully sent.
SK_NOT_FOUND Socket could not be found.
SK_PROCESS_SOCKET Socket is in the process of sending.
SK_TIMEOUT Time out opening socket.
Example
char sockName1[ ] = "SendSocket";
char holdingReg[100];
int result;
while ((result=ADM_receive_sk(sockName1, holdingReg, &readLen, fromIP)) ==
SK_PROCESS_SOCKET);
if(result == SK_SUCCESS){
printf("Received data!\n");
printf("Length == %d\n", readLen);
for (i=0; i<readLen; i++)
{
printf("%c", *(holdingReg+i));
}
printf("\n");
} else {
printf("Received no data Error: %d\n",result);
