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
