INTRO(3) Linux Programmer's Manual INTRO(3)NAME
intro - Introduction to library functions
DESCRIPTION
Section 3 of the manual describes all library functions excluding the library functions (system call wrappers) described in section 2,
which implement system calls.
Many of the functions described in the section are part of the Standard C Library (libc). Some functions are part of other libraries
(e.g., the math library, libm, or the real-time library, librt) in which case the manual page will indicate the linker option needed to
link against the required library (e.g., -lm and -lrt, respectively, for the aforementioned libraries).
In some cases, the programmer must define a feature test macro in order to obtain the declaration of a function from the header file speci-
fied in the man page SYNOPSIS section. In such cases, the required macro is described in the man page. For further information on feature
test macros, see feature_test_macros(7).
CONFORMING TO
Certain terms and abbreviations are used to indicate Unix variants and standards to which calls in this section conform. See standards(7).

My understanding is when you see a man page command with a (3), is that this is a library call such as XSetScreenSaver(3) .. Sometimes these "calls" seem to do exactly what I need from a command. is there a way to access these calls from the terminal and just run them like a normal binary? How... (1 Reply)
Hi,
