Standard library functions

3.12 Standard library functions

Among the standard library functions of the CA78K0R, va_starttop and calls of standard library functions for the near or far pointer whose function name is post-fixed with "_n" or "_f" are converted into standard library functions of the CC-RL. Normal standard library functions are not converted because the same functions are available.

-	Do not use the CcnvCA78K0R to convert the header file of the standard libraries for the CA78K0R and make the CC-RL handle the converted header file. Use the header file of the standard libraries for the CC-RL.

-	Since the function name is converted by replacing strings, if a macro name, variable name, tag name, etc. of the same name exists, they will also be replaced.

The CC-RL does not have a large model. When a C source program for a large model is converted, the type of parameters or return values of standard libraries may not match. Before performing conversion, manually modify the descriptions of the C source program to the standard library functions for the far pointer.
