USING THE STANDARD C LIBRARIES
Building an application which utilizes the standard C libraries requires two types of files:
header files and library files.
2.2.1
All standard C library entities are declared or defined in one or more standard headers
(See list in Section 2.1.3 “Chapter Organization”.) To make use of a library entity in
a program, write an include directive that names the relevant standard header.
The contents of a standard header is included by naming it in an include directive, as in:
#include <stdio.h> /* include I/O facilities */
The standard headers can be included in any order. Do not include a standard header
within a declaration. Do not define macros that have the same names as keywords
before including a standard header.
A standard header never includes another standard header.
2.2.2
The archived library files contain all the individual object files for each library function.
When linking an application, the library file must be provided as an input to the linker
(using the
application may be linked into the application.
A typical C application will require three library files:
libpic30-
more on OMF-specific libraries.) These libraries will be included automatically if linking
is performed using the compiler.

Some standard library functions require a heap. These include the standard
I/O functions that open files and the memory allocation functions. See the
