+.Sh NAME
+.Nm ck_bitmap_size
+.Nd returns necessary number of bytes for bitmap
+.Sh LIBRARY

+.Sh SYNOPSIS
+.In ck_bitmap.h
+.Ft unsigned int
+.Fn ck_bitmap_size "unsigned int n_bits"
+.Sh DESCRIPTION
+The 
+.Fn ck_bitmap_size
+function returns the number of bytes that are necessary
+to allocate for a bitmap that will contain the number
+of bits specified by
+.Fa n_bits .
+.Pp
+This function is used to determine how many bytes to
+allocate for dynamically created bitmap objects. The
+allocated object must still be initialized using 
+.Xr ck_bitmap_init 3 .
+.Sh RETURN VALUES
+This function returns a non-zero value.
