Hi,  
Using MAAPI interface for show commands. While executing one of the show command which takes VRF name, Keypath is coming properly. Passing the VRF-1 to get\_vrf\_rtm\_index. Using this in the maapi\_get\_elem, api, which shows vrf name as some garbage and does not exists and CONFD\_ERR is getting returned and the application is getting close. Can you please suggest what could have caused this .

kp: keypath == /filter-views/rib/instance{VRF-1 ipv4 unicast}/routeRibTemplateList  
get\_vrf\_rtm\_index  
TRACE MAAPI\_GET\_ELEM /vrf-config/stringTOindex{ év\<85\>³}/rtmIndexDEBUG item does not exist - /routing-vrf:vrf-config/stringTOindex{év\<85\>³} does not exist  
–\> CONFD\_ERR

Thanks  
Phani

When calling maapi\_get\_elem() you need to input a path, i.e. a string.

From the confd\_lib\_maapi man page:

> int maapi\_get\_elem(int sock, int thandle, confd\_value\_t \*v, const char \*fmt, …);  
> This reads a value from the path in fmt and writes the result into the result parameter confd\_value\_t. The path must lead to a leaf node in the data tree.  
> …

Can you explain what “get\_vrf\_rtm\_index” does?  
How does the “/vrf-config/stringTOindex{ év\<85\>³}/rtmIndex” path get created?
