I do not know...I was working and when I went to post a thread it said that the page was blocked. It would not let me go to my user CP either. I am sorry if I broke rules, and I promise it will never happen again.

Hello all,
I am trying to figure out what command I can use in AIX in order to find out the driver level for a Fibre Channel adapter. Generically I am able to use "lscfg" to get the details but I am unable to read the output correctly.
Can you help?

pthread_cond_signal
pthread_cond_signal(3C) Standard C Library Functions pthread_cond_signal(3C)
NAME
pthread_cond_signal, pthread_cond_broadcast - signal or broadcast a condition
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include <pthread.h>
int pthread_cond_signal(pthread_cond_t *cond);
int pthread_cond_broadcast(pthread_cond_t *cond);
DESCRIPTION
These two functions are used to unblock threads blocked on a condition variable.
The pthread_cond_signal() call unblocks at least one of the threads that are blocked on the specified condition variable cond (if any
threads are blocked on cond).
The pthread_cond_broadcast() call unblocks all threads currently blocked on the specified condition variable cond.
If more than one thread is blocked on a condition variable, the scheduling policy determines the order in which threads are unblocked. When
each thread unblocked as a result of a pthread_cond_signal() or pthread_cond_broadcast() returns from its call to pthread_cond_wait() or
pthread_cond_timedwait(), the thread owns the mutex with which it called pthread_cond_wait() or pthread_cond_timedwait(). The thread(s)
that are unblocked contend for the mutex according to the scheduling policy (if applicable), and as if each had called
pthread_mutex_lock().
The pthread_cond_signal() or pthread_cond_broadcast() functions may be called by a thread whether or not it currently owns the mutex that
threads calling pthread_cond_wait() or pthread_cond_timedwait() have associated with the condition variable during their waits; however, if
predictable scheduling behavior is required, then that mutex is locked by the thread calling pthread_cond_signal() or pthread_cond_broad-
cast().
The pthread_cond_signal() and pthread_cond_broadcast() functions have no effect if there are no threads currently blocked on cond.
RETURN VALUES
If successful, the pthread_cond_signal() and pthread_cond_broadcast() functions return 0. Otherwise, an error number is returned to indi-
cate the error.
ERRORS
The pthread_cond_signal() and pthread_cond_broadcast() function may fail if:
EINVAL The value cond does not refer to an initialized condition variable.
