1. add support to join main task | static pthread_t self; | | static void *join_task(void *arg) | { | int ret; | ret = pthread_join(self, NULL); <--- /* Fix Task could not be joined */ | return NULL; | } | | int main(int argc, char *argv[]) | { | pthread_t thread; | | self = pthread_self(); | | pthread_create(&thread, NULL, join_task, NULL); | sleep(1); | | pthread_exit(NULL); | return 0; | } 2. Detach active thread will not alloc for additional join, just update the task flag. 3. Remove the return value waiting lock logic (data_sem), the return value will be stored in the waiting tcb. 4. Revise the return value of pthread_join(), consistent with linux e.g: Joining a detached and canceled thread should return EINVAL, not ESRCH https://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_join.html [EINVAL] The value specified by thread does not refer to a joinable thread. NOTE: This PR will not increase stack usage, but struct tcb_s will increase 32 bytes. Signed-off-by: chao an <anchao@lixiang.com> |

ReleaseNotes |
Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
