如何找到给定GArray的长度? [英] How can I find the length of a given GArray?

问题描述

我有一个GValue的GArray(所有非零)，已在运行时使用g_array_append_val进行了分配.我想知道如何找出最后一个元素的索引，或更确切地说是数组包含多少个元素.像这样的代码

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

将失败并超出范围.

推荐答案

它似乎没有很好的文档说明，但是数组中的元素数存储在字段array->len中.

It doesn't seem to be well-documented, but the number of the elements in the array is stored in the field array->len.
