自分の下位コードライブラリ(8)——関数呼び出しスタックを取得する

18684 ワード

今日はツールクラスを置いて、現在のスレッド/すべてのスレッドの現在の関数呼び出しスタックを取得します.
主にlogを打つときに呼び出しスタックを一緒にファイルに出力できるようにするためです.
PS:正しいロゴを出すにはPDBファイルに依存する
VSのようなアウトプットウィンドウへの$CALLSTACKの出力
主にdbghelpのいくつかのAPIを使用しています

不要な機能をいくつか剥離し、2つのインタフェースしか提供していません.
//現在のプロセスで指定したスレッド番号のスレッド呼び出しスタックを印刷する
BOOL GetCallstack(std::vector<:string>& callStacks, DWORD dwThreadId);
//現在のプロセスのすべてのスレッドの呼び出しスタックBOOL GetCallstack(std::vector<:string>&callStacks);
次のコードを直接入力します.

試験手順:
2つのスレッドを作成し、各スレッドの中でFunAとFunBのループ呼び出しを行い、スレッドが1 s実行した後、現在のプロセスのすべてのスレッドの現在の呼び出しスタックを印刷します.

#include "CStackWalker.h"

DWORD WINAPI Run(LPVOID lpParam);
void FunB();
void FunA(int a);

int _tmain(int argc, _TCHAR* argv[])
{
	HANDLE hThread[2] = {0};
	for (int i = 0; i < 2; i++)
	{
		hThread[i] = CreateThread(NULL, 0, Run, 0, 0, NULL);
	}

	Sleep(1000);

	std::vector<:string> callStacks;
	g_StackWalker.GetCallstack(callStacks);
	for (int i = 0; i < callStacks.size(); i++)
	{
		printf("%s
