I have done quite a bit of work on a soft rt application under the protection of #ifdefs and only when I got bad rt performance did I begin to suspect that these might not be implemented, and did the test shown below.
#include <pthread.h> #include <stdio.h>
main( ) { #ifdef _POSIX_THREAD_PRIO_INHERIT printf("_POSIX_THREAD_PRIO_INHERIT supported\n"); #else printf("_POSIX_THREAD_PRIO_INHERIT not supported\n"); #endif #ifdef _POSIX_THREAD_PRIO_CEILING printf("_POSIX_THREAD_PRIO_CEILING supported\n"); #else printf("_POSIX_THREAD_PRIO_CEILING not supported\n"); #endif }
both are supposedly unsupported, which I find very suprising, since my understanding is that linux threads are esentially processes under the hood, and it's a simple matter to change the priority of a process. Am I doing something stupid with the above? I'm sorry if this question is remedial, but I have asked elsewhere and gotten no response.
