Hi.
I came across that fputc() is connected with printf() and fgetc is connected with scanf() in cortex-m3 uVision Keil firmware program.
But I can't find exactly how does it connect between them.
Would you please let me know exactly where can I find the connections?
It's called retargetting.

Probably in a materially similar way to how the library code for stdio does on a PC and most C compilers since the dawn of time.
Thanks but can you let me know where is exactly it I can't find it. what I mean is I want to know the connection between printf() and fputc(). Would you please let me know?
