c - execl() 导致应用程序崩溃

Question

我使用 TCC 编译并运行了以下程序在 Windows 7 下出现应用程序崩溃:

#include <process.h>

int main(void)
{
    if (execlp("c:\\windows\\system32\\whoami.exe", "c:\\windows\\system32\\whoami.exe") < 0)
        perror("error");

    return 1;
}

这里是崩溃的详细信息:

Answer 1

您忘记以 null 终止您的 execlp() 参数列表。

参见例如http://linux.die.net/man/3/execlp或 http://msdn.microsoft.com/en-us/library/vstudio/1kxct8h0.aspx .
