window

Syntax

 
#include <conio.h>

void    window(int _left, int _top, int _right, int _bottom);

Portability

ANSI/ISO C No
POSIX No

Implementation Note

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 gppconio_init function manually (this is the function called by a static constructor).
