POSIX线程是否等同于SYS/BIOS中的Task线程，谢谢！

尊敬的工程师：

您好，我看到MSP432中关于网络的部分都使用了POSIX线程，这个POSIX线程是不是等同于我们SYS/BIOS的Task线程？我是不是都可以使用Task线程来替换这个POSIX线程，还是说这些网络的例程只能使用POSIX线程，谢谢！

祝您好心情

POSIX is an IEEE industry API standard for OS compatibility. POSIX is not an RTOS. It resides on top of either TI-RTOS or FreeRTOS. As you can see with the following diagram, POSIX hides the underlying RTOS from the application.

SYS/BIOS also provides a subset of the POSIX thread (pthread) APIs. These include pthread threads,mutexes, read-write locks, barriers, and condition variables. The pthread APIs can simplify porting applications from a POSIX environment to SYS/BIOS, as well as allowing the same code to be compiled to run in a POSIX environment and with SYS/BIOS. As the pthread APIs are built on top of the SYS/BIOS Task and Semaphore modules, some of the POSIX APIs can be called from SYS/BIOS Tasks.

processors.wiki.ti.com页面上旧的“ SYS / BIOS中的POSIX支持”的内容已移至POSIX用户指南文档中，该文档现在已包含在SDK中。例如：在以下页面上搜索POSIX：
