redirect_stdin
redirect_stdin([stream])
Like redirect_stdout, but for STDIN. Note that the order of the return tuple is still (rd,wr), i.e. data to be read from STDIN, may be written to wr.
Examples
-
Redirect STDIN to a file:
julia> file = open("input.txt", "w"); julia> redirect_stdin(file);This example redirects the STDIN stream to a file named "input.txt". All subsequent input read from STDIN will be read from this file.
-
Restore STDIN after redirection:
julia> original_stdin = redirect_stdin();This example restores the STDIN stream to its original source after redirection. The
redirect_stdin()function without an argument returns the original STDIN stream.
Common mistake example:
julia> redirect_stdin(10)
ERROR: MethodError: no method matching redirect_stdin(::Int64)In this example, a non-stream argument is provided to redirect_stdin(). The function expects a stream object to redirect STDIN, not an integer or any other type. Make sure to provide a valid stream object as an argument to redirect_stdin().
