Moved to haskell café I do not have a code example, but how about a system that compiles different (and say independent) software projects in parallel, and which uses the same code to create temporary files needed for compilation? konst

hi, is there (in Haskell) a function like existFile :: FilePath -> IO (Bool) ? Thanks!

Using such a function is generally a bad idea because of race conditions.

however, real world programs use those tests since you don't need to care *everytime* about race conditions. (of course using this existFile before creating a temporary file is wrong, but existFile has *many* other applications)

Could someone post an example of the creation of a temporary file where race conditions are important?

Thanks,
