c - stat function returns empty struct -

this question has answer here:

• issue s_isdir() result in c (maybe because stat() isn't setting struct properly?) 1 answer

studentsdir = opendir(linevalues); while ((entry = readdir(studentsdir)) != null) {     stat(path, &dirdata);     if (s_isdir(dirdata.st_mode) && (entry->d_name[0] != '.')             && (entry->d_name[1] != '.')) { 

im searching in directory folders. problem stat returns dirdata empty values of folders

the code needs:

  #include <sys/types.h>   #include <sys/stat.h>   #include <unistd.h> 

the prototype function is:

  int stat(const char *path, struct stat *buf); 

so need:

struct stat dirdata; 

and *path variable needs actual path (can relative or absolute), file name, target file.

nothing in posted code indicates of above has been included in code.

and 'entry' pointer 'struct dirent' current file/directory name needs appended 'path' before stat() uses it.

'entry' needs checked assure not null before using it.

the struct dirent contains d_name[256] field contain name of current file (or directory) (but not whole path) each time code steps (sub) directory, (which posted code not doing) path needs have string d_name[] appended path string
