vt_term - optional user defined terminator element
#define GVT_TERM '\0'
When macro GVT_TERM is defined during vt_instantiation(7), the resulting vector is terminated. Termination means genvector always inserts a terminator entry after the last real element of the array. For this, the allocated size (field: alloced) of the array is always kept at least one element larger than the real size (field: used), even when the array is empty (used==0). Most of the vt_ calls maintain the terminator record to make sure the vector is always properly terminated.An exception is the low level call vt_resize(3), which manipulates the alloced field and the actual memory allocation but does not always update the used field and never adds a terminator. vt_uninit(3) also removes the terminator while free'ing the array.
The terminator record is not constructed (vt_construction(7)) or initialized (vt_init_elem(7)).
If the macro is not defined, the vector is non-terminated: no terminator element is added automatically.
