NAME

Intro − introduction to user-level library functions

DESCRIPTION

Section 3 describes user-level library routines.  In this release, most user-library routines are listed in alphabetical order regardless of their subsection headings.  (This eliminates having to search through several subsections of the manual.)  However, due to their special-purpose nature, the routines from the following libraries are broken out into the indicated subsections:

• The Lightweight Processes Library, in subsection 3L. 

• The RPC Services Library, in subsection 3R. 

• The System V Compatibility Library, in subsection 3V.  This library contains System V versions of functions that are not yet merged into the standard Sun libraries.  To use them functions, compile programs with /usr/5bin/cc, instead of /usr/bin/cc. 

The main C library, /usr/lib/libc.a, contains many of the functions described in this section, along with entry points for the system calls described in Section 2.  This library also includes the Internet networking routines listed under the 3N subsection heading, and routines provided for compatibility with other UNIX operating systems, listed under 3C.  Functions associated with the “standard I/O library” are listed under 3S. 

User-level routines for access to data structures within the kernel and other processes are listed under 3K.  To use these functions, compile programs with the −lkvm option for the C compiler, cc(1V). 

Math library functions are listed under 3M.  To use them, compile programs with the the −lm cc(1V) option. 

Various specialized libraries, the routines they contain, and the compiler options needed to link with them, are listed under 3X.
