When the standard library or mathematical library is used in an application, include the related header files to use the library function. |
Refer these libraries using the optimizing linker option (-l).
However, it is not necessary to refer the libraries if only "program diagnosis function", "function with a variable arguments", "character conversion functions" and "character classification functions" are used.
The operation runtime function is a routine that is automatically called by the CC-RH when a floating-point operation or integer operation is performed. |
Unlike the other library functions, the "operation runtime function" is not described in the C source or assembler source.
Each rh***.lib library includes the contents of libc.lib, libm.lib, and libmf.lib (but does not include libmalloc.lib, libsetjmp.lib). When specifying an rh***.lib library, do not specify libc.lib, libm.lib, or libmf.lib together. In addition, only one of the rh***.lib libraries should be specified. Otherwise, correct operation is not guaranteed. |
