下面是获取执行应用程序的完整路径的代码:

变量声明:

char pBuf[256];
size_t len = sizeof(pBuf); 

窗口:

int bytes = GetModuleFileName(NULL, pBuf, len);
return bytes ? bytes : -1;

Linux:

int bytes = MIN(readlink("/proc/self/exe", pBuf, len), len - 1);
if(bytes >= 0)
    pBuf[bytes] = '\0';
return bytes;

对于Win32, GetCurrentDirectory应该做到这一点。

If you fetch the current directory when your program first starts, then you effectively have the directory your program was started from. Store the value in a variable and refer to it later in your program. This is distinct from the directory that holds the current executable program file. It isn't necessarily the same directory; if someone runs the program from a command prompt, then the program is being run from the command prompt's current working directory even though the program file lives elsewhere.

getcwd是一个POSIX函数，所有POSIX兼容平台都支持它。你不需要做任何特殊的事情(除了在Unix上包含正确的头文件unistd.h和在windows上包含direct.h)。

由于您正在创建一个C程序，它将链接到默认的C运行时库，该库由系统中的所有进程链接(避免特别设计的异常)，默认情况下它将包含这个函数。CRT从来不被认为是一个外部库，因为它为操作系统提供了基本的标准兼容接口。

在windows上，getcwd函数已弃用，而支持_getcwd。我觉得你可以这样用。

#include <stdio.h>  /* defines FILENAME_MAX */
#ifdef WINDOWS
    #include <direct.h>
    #define GetCurrentDir _getcwd
#else
    #include <unistd.h>
    #define GetCurrentDir getcwd
 #endif

 char cCurrentPath[FILENAME_MAX];

 if (!GetCurrentDir(cCurrentPath, sizeof(cCurrentPath)))
     {
     return errno;
     }

cCurrentPath[sizeof(cCurrentPath) - 1] = '\0'; /* not really required */

printf ("The current working directory is %s", cCurrentPath);

对于控制台的Windows系统，可以使用system(dir)命令。控制台提供目录等信息。在cmd下阅读有关dir命令的信息。但是对于类unix系统，我不知道…如果执行了该命令，请读取bash命令。Ls不显示目录…

例子:

int main()
{
    system("dir");
    system("pause"); //this wait for Enter-key-press;
    return 0;
}

linux bash命令 哪个progname将报告程序的路径。

即使可以在程序中发出which命令，并将输出定向到tmp文件和程序 随后读取TMP文件，它不会告诉您该程序是否是正在执行的程序。它只告诉您具有此名称的程序位于何处。

所需要的是获取进程id号，并解析出该名称的路径

在我的程序中，我想知道程序是否 从用户的bin目录或路径中的其他目录执行 或者从/usr/bin。/usr/bin将包含受支持的版本。 我的感觉是在Linux中有一个可移植的解决方案。

只是迟来的堆砌在这里，…

没有标准的解决方案，因为这些语言不知道底层文件系统，所以正如其他人所说，基于目录的文件系统的概念超出了c / c++语言的范围。

on top of that, you want not the current working directory, but the directory the program is running in, which must take into account how the program got to where it is - ie was it spawned as a new process via a fork, etc. To get the directory a program is running in, as the solutions have demonstrated, requires that you get that information from the process control structures of the operating system in question, which is the only authority on this question. Thus, by definition, its an OS specific solution.
