Arm Compiler Arm C and C++ Libraries and Floating-Point Support User Guide : The C library scanf family of functions

The C library scanf family of functions

The scanf() family consists of scanf() and fscanf().

These functions depend only on the functions fgetc(), __FILE, and __backspace().

The standard input function of the form scanf(...) is equivalent to:

fscanf(& __stdin, ...)

where __stdin is of type __FILE.
