Thanks! jl_error() is what I want here.

 You mean, running a test suite? See 
 http://docs.julialang.org/en/latest/stdlib/test/ 

 and how most packages do this, for example

Re: [julia-users] Can I throw an error in c code just like Rcpp's stop() in Julia

[Elliot Saba]

No, I think what is wanted here is an analogue to Rcpp::stop(), which looks
like it throws an R error

from
within C/C++ code.  I believe the intent here is to generate
high-level-language errors from low(er)-level-language libraries.

Isn't it the opposite of that though? I.e. catching C++ assert failures?

Ah, I see. You want to trap assertion failures happening in C/C++ from
Julia. Thanks for clarifying.

Re: [julia-users] Can I throw an error in c code just like Rcpp's stop() in Julia

In C or C++ code, I have a function:

void funcname(...){
   ...
   assert(0);
   ...
}

 if I run `ccall((:funcname, libpath), Void, (...), ...)` in Julia , it 
 will  terminate the Julia process.

How can I replace assert() with other function to throw an error in Julia?

Re: [julia-users] Can I throw an error in c code just like Rcpp's stop() in Julia

[良无]

If you want to release an R package to CRAN, R Core will force you to check 
this by R CMD check:

- Compiled code should never terminate the R process within which it is 
running. Thus C/C++ calls to assert/abort/exit, Fortran calls to STOP and 
so on must be avoided. Nor may R code call q().

It's the same people answering in both places. Once you get an answer in

Since I have no idea what Rcpp::stop() or R CMD check do, it's hard to

[julia-users] Can I throw an error in c code just like Rcpp's stop() in Julia

[良无]

In my origin C++ code, I use assert(), but if I want to use this code in 
Julia, maybe I need to replace it with other functions. In R, I can use 
Rcpp::stop(). Is there any easy way to do it in Julia with C or C++ code.

And it seems that Julia does not have R CMD check like stuff yet. It does 
not check this kind of issue.

Thanks.
