NAME

array_length - get number of allocated members in array

SYNTAX

#include <libowfat/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.
