FillConsoleOutputCharacterW（）C ++错误(FillConsoleOutputCharacterW() C++ error)

FillConsoleOutputCharacterW（）C ++错误(FillConsoleOutputCharacterW() C++ error)

当这部分代码运行时，我收到运行时错误：

void PrintChar(int x, int y, char ch, Colors color) { COORD c = {y,x}; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, NULL); FillConsoleOutputAttribute(GameData::handle, color, 1, c, NULL); }

错误是它覆盖了位置0x00000000

有人可以解释为什么这个错误会出现一个例子吗？

GameData类 -

class GameData { public: static CRITICAL_SECTION cs; static void * handle; static GameStates gameState; static int speed; static int level; static int points; static int nextShape; static int nextTurnShape; };

颜色 -

enum Colors { Black, DarkBlue, Green, Blue, Red, Purple, Yellow, While, Gray, LightDarkBlue, LightGreen, LightBlue, LightRed, LightPurple, LightYellow, BrightWhile };

PS

如果我需要提供更多代码来澄清正在发生的事情，请告诉我。

I'm getting a runtime error whenver this section of code runs:

void PrintChar(int x, int y, char ch, Colors color) { COORD c = {y,x}; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, NULL); FillConsoleOutputAttribute(GameData::handle, color, 1, c, NULL); }

The error is that it is overwriting location 0x00000000

Could someone explain why this error comes up with an example please?

GameData class -

class GameData { public: static CRITICAL_SECTION cs; static void * handle; static GameStates gameState; static int speed; static int level; static int points; static int nextShape; static int nextTurnShape; };

Colours -

enum Colors { Black, DarkBlue, Green, Blue, Red, Purple, Yellow, While, Gray, LightDarkBlue, LightGreen, LightBlue, LightRed, LightPurple, LightYellow, BrightWhile };

P.S.

Please let me know if I need to provide any more code to clarify what is going on.

如果您查看该API的文档： https ： //msdn.microsoft.com/en-us/library/windows/desktop/ms682663（v = vs。85）.aspx

您应该传递一个DWORD变量的地址，该变量接收实际写入控制台屏幕缓冲区的字符数

void PrintChar(int x, int y, char ch, Colors color) { DWORD dwNumOfCharsWritten; COORD c = {static_cast<short>(y), static_cast<short>(x)}; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, &dwNumOfCharsWritten); FillConsoleOutputAttribute(GameData::handle, color, 1, c, &dwNumOfCharsWritten); }

If you look at the documentation of that API: https://msdn.microsoft.com/en-us/library/windows/desktop/ms682663(v=vs.85).aspx

You should pass the address of a DWORD variable that receives the number of characters actually written to the console screen buffer

void PrintChar(int x, int y, char ch, Colors color) { DWORD dwNumOfCharsWritten; COORD c = {static_cast<short>(y), static_cast<short>(x)}; FillConsoleOutputCharacterW(GameData::handle, ch, 1, c, &dwNumOfCharsWritten); FillConsoleOutputAttribute(GameData::handle, color, 1, c, &dwNumOfCharsWritten); }
