position
position(s)
Get the current position of a stream.
Examples
In the Julia programming language, the function position(s) is used to get the current position of a stream s. It returns the position as an integer.
julia> io = IOBuffer("Hello, world!")
IOBuffer(data=UInt8[...], readable=true, writable=false, seekable=true, append=false, size=13, maxsize=Inf, ptr=1, mark=-1)
julia> position(io)
1This example demonstrates how to get the current position of a stream io. The initial position is at index 1.
Common mistake example:
julia> str = "Hello, world!"
julia> position(str)
ERROR: MethodError: no method matching position(::String)In this example, the position function is called with a String object instead of a stream. It's important to ensure that the function is used with a stream object for it to work correctly.
