[Rd] C function with unknown output length

[Vincent Goulet]

Hi all,

Could anyone point me to one or more examples in the R sources of a C  
function that is called without knowing in advance what will be the  
length (say) of the output vector?

To make myself clearer, we have a C function that computes  
probabilities until their sum gets "close enough" to 1. Hence, the  
number of probabilities is not known in advance.

I would like to have an idea what is the best way to handle this  
situation in R.

Thanks in advance!
