Memory allocate and deallocate

Note: readdir is the readdir c runtime function.
 
 
Just curious to know what deallocate the memory that return from
readdir(dir_ptr).  I try to do "dealloc myDirEnt_Ptr" right before the
next readdir and the program failed.  I guess that is not necessary. 
 
 
D myDirEnt        ds                  likeds(dirent)     
D                                     based(myDirEnt_Ptr)
D myDirEnt_Ptr    s               *                      

C                   eval      myDirEnt_Ptr = readdir(dir_Ptr) 
C                   dow       myDirEnt_ptr <> *null           
                                                              
C                   ... do something
                                                              
c                   eval      myDirEnt_Ptr = readdir(dir_Ptr) 
C                   enddo
