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.	(Where required, these feature test macros must be defined before including any header files.)	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).
