c - GHashTable (glib2) 线程安全吗？

Question

我有多个线程在 GHashTable 中添加、修改和查找数据。是线程安全的，还是需要自己实现线程安全？

Answer 1

The documentation很清楚地说明了这一点:

After calling g_thread_init(), GLib is completely thread safe (all global data is automatically locked), but individual data structure instances are not automatically locked for performance reasons. So, for example you must coordinate accesses to the same GHashTable from multiple threads.

所以:不，哈希表不是线程安全的。
