 astMalloc 
   Allocate memory  
      
Description: 
 This function allocates memory in a
similar manner to the standard C " malloc" function, but with improved security
(against memory leaks, etc.) and with error reporting. It also allows zero-sized memory
allocation (without error), resulting in a NULL returned pointer value.  
 Synopsis 
 void
astMalloc(
size_t size )  
 Parameters: 
  size  
 The size of the memory region required (may be
zero).  
    Returned Value 
  astMalloc()  
 If successful, the function returns a pointer
                                                                                       
                                                                                       
to the start of the allocated memory region. If the size allocated is zero, this will
be a NULL pointer.
