Hi all!
Is there a function in c++ to create new threads.I have writen a class "Thread"
in which I will be calling this thread function to creat threads.
Also is there a function to synchronize threads .I know that we can create objects like semaphores and critical sections to synchronize in windows apps.But is there a similar function or object which can be used on solaris systems.Thanks for ur help.

use man pages.. you can use the lpthread library direct in your C++ code. if you read the man pages there are samples on how to use the function and other functions related to threads.
dear sir/madam
presently i am in a process of creating a multithread pool using
clone() system call in unix with c programming.
i am facing some problem ie., i am able create multithread pool and
able to keep all the threads in wait state,but when i call kill

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)

pthread_self
PTHREAD_SELF(3) Linux Programmer's Manual PTHREAD_SELF(3)NAME
pthread_self - obtain ID of the calling thread
SYNOPSIS
#include <pthread.h>
pthread_t pthread_self(void);
Compile and link with -pthread.
DESCRIPTION
The pthread_self() function returns the ID of the calling thread. This is the same value that is returned in *thread in the pthread_cre-
ate(3) call that created this thread.
RETURN VALUE
This function always succeeds, returning the calling thread's ID.
ERRORS
This function always succeeds.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
POSIX.1-2001, POSIX.1-2008.
NOTES
POSIX.1 allows an implementation wide freedom in choosing the type used to represent a thread ID; for example, representation using either
an arithmetic type or a structure is permitted. Therefore, variables of type pthread_t can't portably be compared using the C equality
operator (==); use pthread_equal(3) instead.
Thread identifiers should be considered opaque: any attempt to use a thread ID other than in pthreads calls is nonportable and can lead to
unspecified results.
Thread IDs are guaranteed to be unique only within a process. A thread ID may be reused after a terminated thread has been joined, or a
detached thread has terminated.
The thread ID returned by pthread_self() is not the same thing as the kernel thread ID returned by a call to gettid(2).
