获取可执行文件的全路径和所属目录

主要代码：

?

int GetCurFilePath(char *lpOut)                 // get full path of the executable file

{

    char chPath[BUFSIZ] = {0};

    int nRetVal = readlink("/proc/self/exe", chPath, sizeof(chPath)); // get full path of the current-executable file

    if(nRetVal < 0)

    {

        strcpy(lpOut, ".");

        return -1;

    }

    else

    {

        strcpy(lpOut, chPath);

        return 0;

    }

}

 

int GetCurDir(char *lpOutDir)                       // get directory-path of current executable-file

{

    char    chPath[BUFSIZ] = { 0 };

    if( GetCurFilePath(chPath) < 0 )

        return - 1;

    dirname(chPath);                                    // dirname will change value of "chPath"(contain result)

    strcpy(lpOutDir, chPath);                       // copy result to out-param

 

    return 0;

}

上面的BUFSIZ是库函数中定义的宏，值为8192

可能需要的头文件有：

#include <unistd.h> ： readlink
#include <string.h> ：strcpy ...
#include <libgen.h> ：dirname
