To allow your embedded code to have callbacks from perl, you can compile .xs file(s) having XS functions doing the desired tasks. Your C library would create the bootstrap function for your module (like done in the example xs_init function in perlembed) and call the bootstrap method for the XS module (a task ordinarily be done by a .pm file, which if may be a better place to put this if you provide real .pm files somehow). If you do not want to divide your code into perl embedding files and perl XS files, you can put most of your non-XS code at the top of the .xs file(s) before the MODULE = line.

You may find it helpful to look at the perl embeding portions of a program that embeds perl like this, for example, VIM (which I used to derive some of this information.)
