the <dirent.h> library has the following functions

int            closedir(DIR *);
DIR           *opendir(const char *);
struct dirent *readdir(DIR *);
int            readdir_r(DIR *, struct dirent *, struct dirent **);
void           rewinddir(DIR *);
void           seekdir(DIR *, long int);
long int       telldir(DIR *);

if you're confined to Windows-specific solutions, theres an implementation of this for Windows
http://www.gimp.org/~tml/gimp/win32/dirent.zip

if that's not acceptable for homework purposes, then maybe you can just get away with a system call like strcpy(myBigString, system("dir")); .

It would be best to let us know what O/S and compiler you are using so we don't have to guess, as jephthah was forced to do. They all have different ways to accomplish the task.
