[Rcpp-devel] experimental handling of uncaught exceptions

[Romain François]

Hi,

I've commited some code that aims at forwarding uncaught C++ exceptions 
to R.

For example :

require( Rcpp)
funx <- cfunction(signature(), '
throw std::range_error("boom") ;
return R_NilValue ;
', Rcpp=TRUE, verbose=FALSE)
tryCatch(  funx(), "C++Error" = function(e){
	print( "gotcha" )
} )
print( rnorm(10) )

This is experimental so it will need to be reviewed.

This is based on this page :
