* Name: readdir_r
*
* Description:
* The readdir() function returns a pointer to a dirent
* structure representing the next directory entry in the
* directory stream pointed to by dir. It returns NULL on
* reaching the end-of-file or if an error occurred.
*
* Inputs:
* dirp -- An instance of type DIR created by a previous
* call to opendir();
* entry -- The storage pointed to by entry must be large
* enough for a dirent with an array of char d_name
* members containing at least {NAME_MAX}+1 elements.
* result -- Upon successful return, the pointer returned
* at *result shall have the same value as the
* argument entry. Upon reaching the end of the directory
* stream, this pointer shall have the value NULL.
*
* Return:
* If successful, the readdir_r() function return s zero;
* otherwise, an error number is returned to indicate the
* error.
*
* EBADF - Invalid directory stream descriptor dir
