Error while including libraries

Hi All,

When i am trying to include graphics.h ,dos.h and conio.h, its giving error as follows:

pgm.c:2:17: dos.h: No such file or directory
pgm.c:3:22: graphics.h: No such file or directory
pgm.c:4:19: conio.h: No such file or directory

Whereas stdio.h, stdlib.h and time.h gets included.

What could be the reason for this. And how can it be resolved.

Which OS, which compiler? If it a UNIX, you're out of luck anyways, as dos.h, conio.h, and graphics.h are MS specific headers, found only on DOS and newer.

Sometimes Borland has them.

But since there are no Borland compilers for UNIX, the result is pretty much the same.
