[Format]

-simple_stdio

[Description]

-

This option creates a functional cutdown version of I/O functions.

-

The functional cutdown version does not include the conversion of floating-point numbers (same as the function not supported with the nofloat option), the conversion of long long type, and the conversion of 2-byte code. When inputting or outputting files that do not require these functions, ROM can be saved.

Target functions:fprintf, fscanf, printf, scanf, sprintf, sscanf, vfprintf, vprintf, and vsprintf

[Remarks]

-

In a library created with this option specified, correct operation cannot be guaranteed when a cutdown function is used in the target functions.

-

This function is disabled during C++ and EC++ program compilation.
