Although it is slightly dated, I can still recommend "The Unix 
Programming Environment" by Brian Kernighan and Rob Pike:

  http://cm.bell-labs.com/cm/cs/upe/

It is not specific to Linux, but it will give you a good basis in the 
concepts you need to program Linux and other Unix-like systems.  You 
might also consider Eric S. Raymond's "The Art of Unix Programming":

Incidentally, the main() function of a C program is supposed to have a 
return type of int, as per the ISO C standard.  Most compilers will 
accept a non-standard main() that yields void, but that is not a Linux 
vs. Windows issue.
