- * Name: avsprintf
- *
- * Description:
- *   This function is similar to vsprintf, except that it dynamically
- *   allocates a string (as with malloc) to hold the output, instead of
- *   putting the output in a buffer you allocate in advance.  The ptr
- *   argument should be the address of a char * object, and a successful
- *   call to avsprintf stores a pointer to the newly allocated string at that
- *   location.
- *
- * Returned Value:
- *   The returned value is the number of characters allocated for the buffer,
- *   or less than zero if an error occurred. Usually this means that the buffer
- *   could not be allocated.
- *
