introduction to the C libraries
This section provides an overview of the C library functions,
their error returns and other common definitions and concepts. Most of these
functions are available from the System library,
libSystem.
Other libraries must be indicated at compile time with the
-l
option of the compiler.
The various libraries (followed by the loader flag):
-l
System)-l
System for
these functions. There are several `libraries' or groups of functions
included inside of libSystem: the
standard I/O routines, database routines, bit operators, string operators,
character tests and character operators, des encryption routines, storage
allocation, time functions, signal handling and more.
For compatibility with other systems, which provide these
capabilities in separate libraries (such as
libc), symbolic links are provided
for -l
c,
-l
dbm,
-l
dl,
-l
info,

to libSystem.
