用win32 api写一个通过进程名称获取进程路径并且返回的C语言代码

以下是一个通过进程名称获取进程路径并返回的C语言代码：

#include <windows.h>
#include <tlhelp32.h> //需要包含tlhelp32.h头文件

// 获取指定进程的路径
BOOL GetProcessPathByName(const WCHAR* processName, WCHAR* processPath, DWORD processPathLength)
{
    HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
    if (snapshot == INVALID_HANDLE_VALUE)
    {
        return FALSE;
    }

    PROCESSENTRY32 processEntry = { 0 };
    processEntry.dwSize = sizeof(PROCESSENTRY32);

    if (Process32First(snapshot, &processEntry))
    {
        do
        {
            if (wcscmp(processEntry.szExeFile, processName) == 0)
            {
                wcscpy_s(processPath, processPathLength, processEntry.szExeFile);
                PathRemoveFileSpec(processPath);
                PathAddBackslash(processPath);
                wcscat_s(processPath, processPathLength, processName);
                CloseHandle(snapshot);
                return TRUE;
            }
        } while (Process32Next(snapshot, &processEntry));
    }

    CloseHandle(snapshot);
    return FALSE;
}

int main()
{
    WCHAR processName[] = L"notepad.exe";
    WCHAR processPath[MAX_PATH] = { 0 };

    if (GetProcessPathByName(processName, processPath, MAX_PATH))
    {
        wprintf(L"The path of %s is %s\n", processName, processPath);
    }
    else
    {
        wprintf(L"Failed to get the path of %s\n", processName);
    }

    return 0;
}

以上代码使用了Windows API中的CreateToolhelp32Snapshot和Process32First/Process32Next函数来遍历系统中所有的进程，并且通过进程名称进行匹配，最终获取到进程路径。
