[参考译文] PROCESSOR-SDK-J784S4：J784S4：如何在 QNX 上将 pthread 堆栈大小设置为8MB

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1432390/processor-sdk-j784s4-j784s4-how-to-set-pthread-stack-size-to-8mb-on-qnx

工具与软件：

您好、TI 专家！

打印的栈大小值  Thread_attr  将其初始化  pthread_attr_init (&thread_attr)； 使用  pthread_attr_getstacksize  那么您将获得以下结果：

Linux OS：8388608 (8MB)

QNX OS：0

我们如何  在 QNX 上将 pthread 的栈大小设置为8MB、就像在 Linux 上一样？
