getpid

getpid() -> Int32

Get julia's process ID.

Examples

In the Julia programming language, the function getpid()

Retrieve Julia's process ID as an Int32 value.

julia> getpid()
12345

Here are some common examples of how getpid() can be used:

1. Print Julia's process ID:

   julia> println(getpid())
   12345

   This example retrieves Julia's process ID and prints it.

2. Store process ID in a variable:

   julia> pid = getpid()
   12345

   Here, the process ID is stored in a variable named pid for further use.

3. Use process ID in a system call:

   julia> pid = getpid()
   12345
   julia> run(`echo $pid`)
   12345

   In this example, the process ID is used in a system call to echo the process ID itself.

Common mistake example:

julia> getpid
ERROR: syntax: missing parentheses in call to "getpid"

In this example, the parentheses are missing when calling the getpid() function. It's important to include the parentheses () when calling a function in Julia to avoid syntax errors.
