Library Functions And Header Files - Epson S5U1C17001C Manual

4.2.2 library functions and Header files

This package contains an ANSI library and an emulation library for calculating floating-point numbers and the
remainders of divided integral numbers.
The header files in the "include" directory contain library function declarations and macro definitions. When using
a library function, include the header file that contains its declaration by using the #include instruction.
Certain ANSI library functions not supported by this package are not included in the ANSI library.
The client assumes responsibility for function implementation and prototype declarations when using ANSI library
functions not supported by this package.
For some ANSI library functions not supported by this package, the header files include only prototype
declarations. In these cases, include the pertinent header file rather than declaring a prototype before implementing
the function.
The following table shows the relationship between the types of library files and header files.

For details about the functions included in the libraries, refer to Chapter 7, "Library".
When using a library function, be sure to specify the library file that contains the function used when linking. The
linker extracts only the necessary object modules from the specified library file as it links them.
