如何找到给定GArray的长度？

Question

I have a GArray of GValue (all non-zero) which has been allocated at runtime with g_array_append_val. I wonder how can I find out what's the index of the last element, or more precisely how many elements does the array hold. Code like

for (length=0;g_value_get_int(&g_array_index(array, GValue, length)); length++);
return length

would fail with an out of bounds.

Answer 1

它似乎没有详细记录，但数组中元素的数量存储在字段array->len 。
