Getting terminal size in c for windows?

Question

How to check ymax and xmax in a console window, under Windows, using plain c?

There is this piece of code for linux:

Answer 1

This prints the size of the console, not the buffer:

#include 

int main(int argc, char *argv[]) {
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    int columns, rows;

    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    columns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    rows = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;

    printf("columns: %d\n", columns);
    printf("rows: %d\n", rows);
    return 0;
}

This code works because srWindow "contains the console screen buffer coordinates of the upper-left and lower-right corners of the display window", and the SMALL_RECT structure "specify the rows and columns of screen-buffer character cells" according to MSDN. I subtracted the parallel sides to get the size of the console window. Since I got 1 less than the actual value, I added one.
