flush
flush(stream)
Commit all currently buffered writes to the given stream.
Examples
julia> io = open("output.txt", "w")
IOStream(<file output.txt>)
julia> println(io, "Hello, World!")
julia> flush(io)This example demonstrates the use of flush to commit all buffered writes to the specified stream. The println function writes the string "Hello, World!" to the io stream. The flush function ensures that the write operation is immediately committed to the stream.
Common mistake example:
julia> io = open("output.txt", "r")
IOStream(<file output.txt>)
julia> flush(io)
ERROR: MethodError: no method matching flush(::IOStream)In this example, an error occurs because the flush function is called on a read-only stream ("r" mode). The flush function can only be used on writable streams. Make sure to open the stream in a writable mode before using flush.
