- access dynamic thread scheduling
cc –mt [ flag... ] file...[ library... ] #include <thread.h> int thr_setprio(thread_t target_thread, int priority);
int thr_getprio(thread_t target_thread, int *priority);
The thr_setprio() function sets the scheduling priority for the thread specified by target_thread within the current process to the value given by priority.
The thr_getprio() function stores the current priority for the thread specified by target_thread in the location pointed to by priority.
If the thr_setprio() function fails, the scheduling priority of the target thread is not changed.
If successful, the thr_getprio() and thr_setprio() functions return 0. Otherwise, an error number is returned to indicate the error.
The thr_getprio() and thr_setprio() functions will fail if:
The value specified by target_thread does not refer to an existing thread.
The thr_setprio() function will fail if:
The value of priority is invalid for the scheduling policy of the specified thread.
The caller does not have the appropriate permission to set the priority to the value specified.
