myid()

Get the id of the current process.

Examples

In the Julia programming language, the myid() function is used to get the id of the current process.

julia> myid()
1

The myid() function returns the id of the current process, which is typically a positive integer. The exact value of the id may vary depending on the Julia runtime environment.

Common example of its use:

julia> id = myid()
1

julia> println("Current process id: ", id)
Current process id: 1

In this example, myid() is used to obtain the id of the current process and store it in the variable id. The id is then printed to the console.

It's important to note that the output of myid() may differ in multi-threaded or distributed computing scenarios.

Common mistake example:

julia> myid(42)
ERROR: MethodError: no method matching myid(::Int64)

In this example, the mistake is passing an argument to the myid() function. myid() does not take any arguments, so it should be called without any parameters.
