If you are referring to Suspend-to-RAM here, you can install the 'pm-utils'
package and then run the 'pm-suspend' script from the cli to suspend
the machine.

Most distros can be configured to do all that. You need not have to code
anything new. You'll just have to set up the power management policies
appropriately to tell what should happen when your laptop lid is closed
etc.
