NAME
       array_truncate - reduce number of initialized bytes

SYNTAX
       #include <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.
