R devel - Sep 2006 - time_t handling in R

Hello all,

I am converting some C code into a package for R and wondered what the  
proper way of handling time_t types from C in R was.  time_t is a typedef  
for long, but R seems to only deal in Integers or Reals, so what is the  
proper way of handling time in an R to C conversion ( or visa versa )?

Many thanks

Tom

time_t is not portably a typedef for long, or even for an integer type 
(according to the C standard).  If it is an integer type on your system 
then you can pass it as a vector of integer (and on many systems long and 
int are the same so one integer will suffice)
