Hi,
I am trying to grep one variable over the other variable
Example:
i=abc
j=ab
grep $j $i
I am getting this error:
The error is due to $i being variable and not file. I know I could do it by putting the value of abc in a file
and then greping it. (1 Reply)

pthread_detach
pthread_detach(3C) pthread_detach(3C) NAME
pthread_detach - detach a thread SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ] #include <pthread.h> int pthread_detach(pthread_t thread); The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when that thread terminates. In other words, pthread_detach() dynamically resets the detachstate attribute of the thread to PTHREAD_CRE- ATE_DETACHED. After a successful call to this function, it would not be necessary to reclaim the thread using pthread_join(). See pthread_join(3C). If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on the same target thread is unspecified. If successful, pthread_detach() returns 0. Otherwise, an error number is returned to indicate the error. The pthread_detach() function will fail if: EINVAL The implementation has detected that 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.
