#define ADDTO_ARRAY	(	anam,
		typ,
		val	)

Value:

do{ int n=anam->num ;                                          \
     anam->ar = realloc(anam->ar,sizeof(typ)*(n+1)) ;           \
     anam->ar[n] = (val) ; anam->num++ ;             } while(0)

Append element "val" to an array pointer "anam" of type "typ_array *".
