PTHREAD_EQUAL(3) Linux Programmer's Manual PTHREAD_EQUAL(3)NAME
pthread_equal - compare thread IDs
SYNOPSIS
#include <pthread.h>
int pthread_equal(pthread_t t1, pthread_t t2);
Compile and link with -pthread.
DESCRIPTION
The pthread_equal() function compares two thread identifiers.
RETURN VALUE
If the two thread IDs are equal, pthread_equal() returns a nonzero value; otherwise, it returns 0.
ERRORS
This function always succeeds.
CONFORMING TO
POSIX.1-2001.
NOTES
The pthread_equal() function is necessary because thread IDs should be considered opaque: there is no portable way for applications to
directly compare two pthread_t values.

I want to store a bunch of pthread_t types in a hash table, but since pthread_t is not an integer value, I cannot hash it. I was hoping to store a unique nonzero as key 0 for each thread with thread-specific data ala pthread_key_create/pthread_setspecific, but but as it turns out only the first... (2 Replies)
hi
i have a code:
I found that after exiting from child thread memory isn't freed. I commented everything which is "some actions" here, so thread's function contains only two lines. But it doesn't help.
What do I do wrong?
Thanks a lot (3 Replies)

The prototype for pthread_create function is like this:-
int pthread_create(pthread_t *thread,pthread_attr_t *attr,void *(*start routine),void *arg);
Q.1 .Why the return type of the start_routine must be void*??
Q.2. Why should we pass arg by converting into void * only ??
Thank You (3 Replies)

Suppose I declare
pthread_t clear_thread;
and then

the thread is supposed to go away, perform the service it is intended to procide, and then kill itself.
A little while later, I require this service again, so I say
