C Programming Reference
There are two sources of information that you can use for
the C programming language.
The first is a C language quick reference
(in PDF) which gives an overview of the language.
The second reference source is the Unix Programmers’ Manual,
available via the man command. The most useful
material will probably be the library function reference,
available in section 3 of the manual. To access the manual
entry for a particular function, e.g. strlen, use
the command:
man 3 strlen
If you can’t remember the name of the function you want,
use the apropos command to get a list of
suggestions. To use apropos, simply give a
keyword that describes some aspect of the function.
Imagine that you’ve forgotten the name of the strlen
function, but you know there’s a function compute the
length of a string. Try the following command:
apropos length
The apropos command typically gives too many suggestions,
but you can usually find what you want somewhere in the list.
