введение в библиотечные функции (introduction to library functions)
Имя (Name)
intro - introduction to library functions
Описание (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 specified 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).
