NAME¶
intro - Introduction to library functions
DESCRIPTION¶
This chapter describes all library functions excluding the library functions
described in chapter 2, which implement system calls. There are various
function groups which can be identified by a letter which is appended to the
chapter number:
- (3C)
- These functions, the functions from chapter 2 and from
chapter 3S are contained in the C standard library libc, which will be
used by cc(1) by default.
- (3S)
- These functions are parts of the stdio(3S) library.
They are contained in the standard C library libc.
- (3M)
- These functions are contained in the arithmetic library
libm. They are used by the f77(1) FORTRAN compiler by default, but
not by the cc(1) C compiler, which needs the option
-lm.
- (3F)
- These functions are part of the FORTRAN library libF77.
There are no special compiler flags needed to use these functions.
- (3X)
- Various special libraries. The manual pages documenting
their functions specify the library names.
