*Dear All,*
*I was trying to run a bunch of NesC code on the TinyOS simulator TOSSIM.*
*While doing this we were getting the following errors (what follows is a
print of the command prompt log)*
*Error has been highlighted in yellow*

*It seems that it is not able to detect the printfflush function. This
error does not arise during compile time. It is just during run time that
this pops up. Could you please help su find a solution to this error. We
would greatly appreciate any assistance you can provide to us.*
*Thanks in advance,*
*Ak.*
