sleeping

[David Eduardo Gomez Noguera <davidgn servidor unam mx>]

Hello again.

I am writing a program to control two steppers. To control its speed, i would need to sleep the function that moves them.
Is it safe to use sleep/nanosleep? or are there safer functions or a better way to do it than a callback from an Entry widget (where i get the command from)? (I was just thinking a long coulback could hang the app, am i right?)
