#include <conio.h> int _conio_kbhit(void);
Determines whether or not a character is waiting at the keyboard. If
there is an ungetch'd character, this function returns true. Note
that if you include
kbhit (see section kbhit)
function is redefined to be this function instead.
Nonzero if a key is waiting, else zero.
It's not safe to call this function inside static constructors, because conio needs to be initialized, and its initialization is done by a static constructor. Since you don't have any control on the order in which static constructors are called (it's entirely up to the linker), you could have problems.
If you can detect the situation when one of the conio functions is
called for the very first time since program start, you could work
around this problem by calling the
manually (this is the function called by a static constructor).
