array_length(3)       DragonFly Library Functions Manual       array_length(3)

NAME
       array_length - get number of allocated members in array

SYNTAX
       #include <array.h>

       int64 array_length(array* x,uint64 membersize);

         array x;
         int64 members = array_length(&x,sizeof(t));

DESCRIPTION
       array_length returns the number of initialized bytes in x, divided by
       the size of t. In other words, array_get will succeed for positions 0
       through array_length-1; it will fail for position array_length.

       If x is unallocated, array_length and array_bytes return 0.
