Parent Thread Of Child Thread
Suppose a process creates some threads say threadC and threadD.
Later on each of these threads create new child threads say threadC1, threadC2, threadC3 etc. So a tree of threads will get created.
Is there any way to find out the parent thread of one such... (1 Reply)
I, have an output with 3 different values each below the other like:
# echo $bla
Each value is in one line and for the further processing I need every single value.
For example is there a way to grep line 2, like:
# echo $bla | grep --line 2
Thank you in... (6 Replies)
how about asynchronous canceling?
or with signal?
if with signal whether it effects the process?
my english so badly :( :( (1 Reply)

pthread_self(3) Library Functions Manual pthread_self(3)NAME
pthread_self - Obtains the identifier of the calling thread.
DECthreads POSIX 1003.1c Library (libpthread.so)
Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
This routine returns the address of the calling thread's own thread identifier. For example, you can use this thread object to obtain the
calling thread's own sequence number. To do so, pass the return value from this routine in a call to the pthread_getsequence_np(3) routine,
unsigned long this_thread_nbr;
this_thread_nbr = pthread_getsequence_np( pthread_self( ) );
The return value from the pthread_self(3) routine becomes meaningless after the calling thread is destroyed.
Returns the address of the calling thread's own thread object.
