Sorry,I looked at the website you mentioned, but I didn't find the information I wanted.

Hi,

Please check the NDK TI Network Developer's Kit (NDK) v2.25 API Reference Guide for NIMUIOCTL. From Table A-2. IOCTL Commands, I don't think you can set/get an IP address.

Hi Eric,

can I use the CfgAddEntry() function to add a IP Address, if I use the CfgRemoveEntry() to delete it before, while I had used the CfgAddEntry() function to add a IP Address in the initialization phase at the beginning of the program?

other questions：

1. in the example:C:\ti\pdk_am437x_1_0_10\packages\ti\transport\ndk\nimu\example\src\main_AM57xx.c. int the stackInitHook(), it use the hCfg by parameter passing, if I want to use it by global variable in the task, how can I get it?

2. If I want to get current IP address, whoch API can I use ?  can i use the CfgGetImmediate() to get it?

Hi, Eric

I had implemented IP address change, it should to use the CfgRemoveEntry() to delete the original one ,and then use the  CfgAddEntry() to add the new one.

but now, I have a new question:

How to implement the function of attribute SOCKET_FIONBIO and SOCKET_FIONREAD of the Ioctl().

in ioctl, the attribute SOCKET_FIONBIO mean to set socket to non-blocking; the attribute SOCKET_FIONREAD mean  to determine the amount of data pending in the network's input buffer.

Hi Eric,

I studied the NDK API reference manual carefully and found that there are two functions to achieve these two functions.

for non-blocking,use the setsockopt() as follow:

setsockopt(hSocket, SOL_SOCKET, SO_BLOCKING, piParameter, sizeof(int))   

for data length ,use the fdStatus() as follow:

fdStatus(hSocket, FDSTATUS_RECV, piParameter);

the piParameter is pointer to a int.

Do I understand correctly?

Hi,

What is the NDK release you used? I looked 2.26.0.8, the
/*-------------------------------------------------------------------- */
/* fdStatus() (USER FUNCTION) */
/* Called to get the status of a file descriptor */
/*-------------------------------------------------------------------- */
int fdStatus( HANDLE fd, int request, int *presults )

When you use FDSTATUS_RECV for the request, I thought it return socket status, either 0 or 1, not the data length.

Let me check our expert for this.
