OpenServer, previously SCO UNIX and SCO Open Desktop (SCO ODT), is a closed source version of the Unix computer operating system developed by Santa Cruz Operation (SCO), later acquired by SCO Group, and now owned by Xinuos

SCO OpenServer

SCO OpenServer 5, an AT&T UNIX System V Release 3-based operating system, was initially released by The Santa Cruz Operation in 1995. Based on SCO UNIX 3.2v4, SCO OpenServer 5 would become SCO's primary product and serve as the basis for products like PizzaNet (the first Internet-based food delivery system done in partnership with Pizza Hut) and Global Access (the first commercially licensed and bundled Internet Operating System). Due to its large installed base, SCO OpenServer 5 continues to be actively maintained by SCO with major updates having occurred as recently as April 2009.

I noticed that there are two prototypes for open system call in linux,

int open(const char *pathname, int flags);
int open(const char *pathname, int flags, mode_t mode);

I would like to know how the C compiler can differentiate b/w both calls, given C compiler doesn't support function overloading?
