In Go, we cannot directly set the size of the Goroutine stack using runtime.SetStack(). This function is not directly available in the runtime package.
The size of the Goroutine stack is determined by the Go runtime itself, and it is not recommended to manually adjust the stack size. The runtime automatically manages Goroutine stacks and adjusts their size based on the requirements of the program.
However, if you still want to change the default stack size, you can do so using the GODEBUG environment variable. The GODEBUG variable allows us to control various runtime properties, including the stack size.
Here's an example of how to set a custom Goroutine stack size using GODEBUG:
Set the environment variable GODEBUG to include the godefstack parameter, followed by the desired stack size in bytes.
Use the command: export GODEBUG=godefstack=1024000
This will set the Goroutine stack size to 1 MB.
Compile and run your Go program.
With this approach, the runtime will allocate a stack of the specified size for each Goroutine created.
Remember that adjusting the Goroutine stack size is generally not required and can lead to unexpected behavior. It is recommended to leave the stack size to the default provided by the Go runtime.
