NAME
       array_truncate - reduce number of initialized bytes


SYNTAX
       #include <libowfat/array.h>

       void array_truncate(array* x, uint64 membersize, int64 len);

         array_truncate(&x,sizeof(t),len);


DESCRIPTION
       array_truncate  reduces  the  number of initialized bytes in x to exactly len*sizeof(t). If the number of
       initialized bytes was already this small (or smaller), array_truncate has no effect. If len is  negative,
       array_truncate  has  no  effect.  If  x  is  unallocated,  array_truncate has no effect. If x has failed,
       array_truncate has no effect.

       array_truncate does not change the allocation in x. If you want  to  free  the  memory  used  by  x,  use
       array_reset.
