I'm new to linux and c or c++, but i have been using programing languages in the past. Mainly hi level compilers (games). I mainly do this as a hobby. Lately I've decided to use linux (great, I love it) and c++ to program my games. C seems OK to program in (still need to understand OOP better to use C++). But I've run into this problem: Where can I find information on using the function libraries, more specifically I need to now the commands relevant to these libs ie: put_pixel(x,y) printf() or whatever.
