xSemaphore source code

Hello everybody, I’m a new user of FreeRtos and I am trying to undersand how semaphore are managed. My question is quite simple :
There is a semphr.h file, but I can’t find the .c ! Where are xSemaphoreXXXX functions coded ?!
Thanks a lot for your help, Elri07

Semaphores are, primarily, implemented as an abstraction layer above the queues.  If you look in semphr.h you will see each semaphore macro is #defined to a function, most of which are defined in queue.c. Regards.
