Hello, I'm searching for a proper way to let the kernel space ISR(implemented in a kernel module) wake up a user space thread on a hardware interrupt.
Except for sending a real-time signal, is it possible to use a semaphore?
I've searched it on google, but it seems impossible to share a... (0 Replies)

I created a awk state to calculate the number of success however when the query runs it has a leading zero. Any ideas on how to remove the leading zero from the calculation?
Here is my query:

pthread_join
PTHREAD_JOIN(3) BSD Library Functions Manual PTHREAD_JOIN(3)NAME
pthread_join -- wait for thread termination
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_join(pthread_t thread, void **value_ptr);
DESCRIPTION
The pthread_join() function suspends execution of the calling thread until the target thread terminates unless the target thread has already
terminated.
On return from a successful pthread_join() call with a non-NULL value_ptr argument, the value passed to pthread_exit() by the terminating
thread is stored in the location referenced by value_ptr. When a pthread_join() returns successfully, the target thread has been terminated.
The results of multiple simultaneous calls to pthread_join() specifying the same target thread are undefined. If the thread calling
pthread_join() is cancelled, then the target thread is not detached.
A thread that has exited but remains unjoined counts against _POSIX_THREAD_THREADS_MAX.
RETURN VALUES
If successful, the pthread_join() function will return zero. Otherwise an error number will be returned to indicate the error.
ERRORS
pthread_join() shall fail if:
[EINVAL] The value specified by thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to that specified by the given thread ID, thread.
pthread_join() may fail if:
[EDEADLK] A deadlock was detected or the value of thread specifies the calling thread.
SEE ALSO wait(2), pthread_create(3)STANDARDS
The function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
