linuxc当前程序所在目录下,linuxc获得当前进程的进程名和执行路径

如何得到当前进程的进程名和执行路径。写了个程序分享一下

代码如下:

[sam&＃64;hzhsan test]$ more test_processname.cpp

#include

#include

#include

#include

size_t get_executable_path( char* processdir,char* processname, size_t len)

{

char* path_end;

if(readlink("/proc/self/exe", processdir,len) <&＃61;0)

return -1;

path_end &＃61; strrchr(processdir, &＃39;/&＃39;);

if(path_end &＃61;&＃61; NULL)

return -1;

&＃43;&＃43;path_end;

strcpy(processname, path_end);

*path_end &＃61; &＃39;&＃39;;

return (size_t)(path_end - processdir);

}

int main()

{

char path[PATH_MAX];

char processname[1024];

get_executable_path(path, processname, sizeof(path));

printf("directory:%snprocessname:%sn",path,processname);

}
