The standard include header files are located in the following directory:

\include \ std


where <ZDS Installation Directory> is the directory in which Zilog Developer Studio was
installed. By default, this would be

sion> , where <version> might be 4.11.0 or 5.0.0.
Standard Header Files
Each library function is declared in a header file. The header files can be included in the
source files using the
#include preprocessor directive. The header file declares a set of
related functions, any necessary types, and additional macros required to facilitate their
use.
Header files can be included in any order; each can be included more than once in a given
scope with no adverse effect. Header files must be included in the code before the first ref-
erence to any of the functions they declare or types and macros they define.
