//  acutmem.h - General memory allocation functions.
//
//  DESCRIPTION:
//
//  The following functions are used to handle string values and memory
//  returned to or from (or passed into) the ObjectARX API.  Function
//  acutNewString() makes a copy of a string and returns an error status.
//  Function acutUpdString() performs the same job as acutNewString(),
//  except that it first frees any string already pointed to by the
//  output argument.  acutDelString() frees up a string allocated by
//  acutNewString() or acutUpdString() if the input pointer is non
//  NULL and then sets the pointer to NULL.
//
