That is number of lines in the console ?
I know SetConsoleWindowInfo() but I can't find anywhere sheet for corresponding GetConsoleWindowInfo().
Use GetConsoleScreenBufferInfo:
CONSOLE_SCREEN_BUFFER_INFO csbi;
GetConsoleScreenBufferInfo (GetStdHandle (STD_OUTPUT_HANDLE), &csbi);
//use csbi.dwSize for the rows and columns...
If you're on Vista and up you can use the "Ex" form of this as well.
