"Checked in" my code

Today I migrated all the code to use a new header file. The existing code uses a ".h" file that is Windows dependent. Our team developed a ".h" file that has the same functionality but is not-Windows dependent. I was asked to find out all the code in the database that uses the old header file and then make changes to some code in those files so that they work with the newly written header file. I have done that and it worked on my machine. Then I checked in the code into the server. Now I have to wait until tomorrow to see if my code breaks someone else code. If it does break then thats it!!! Everyone will start interrogating me.
