If you know the name of a function but not the header it's in, type man <function name>. For example, 'man strcat' will show you that definition and tell you that it's in string.h.
Some man pages have some examples, or at least an explanation of how you are supposed to do things. You can of course use all those libraries in your C++ code. There is not (at least on my Linux box) documentation in the form of manual pages for the C++ STL or other C++ libraries. There are many good resources online, however, so it's not a huge loss. I do like the convenience of typing 'man printf' when I can't remember all that arcane syntax though... Also, although the following link is really QNX documentation, it some times comes in handy as a reference for ANSI and POSIX C stuff: http://qdn.qnx.com/support/docs/neutrino_2.11_en/lib_ref/about.html If anyone knows of a Linux equivalent, please post it!
