Hello !
Let's supose I have a main function in C , and two POSIX threads. I give you an example down :
int main() {
int something;
char else;
void *FirstThread();
void *SecondThread();
..
<start those two pthreads ..>
return 0;}
void *FirstThread() { ... }
void *SecondThread()... (2 Replies)

HI,
When i am configuring php in SUN Solaris. I am getting the below error.
configure: error: Your system seems to lack POSIX threads.
Do i need to install POSIX? If so can somebody let me know where can i download POSIX for Solaris 8?

I created multiple POSIX threads (on readhat Linux) in a C program in my app. What I am doing is - I am creating threads equal to the number of CPUs in the system and and equal number of instances of a certain data structure, basically a queue implementation. I am assigning one ID to the thread... (2 Replies)
Hi,
I am new to posix threads. The no of threads to be created depends on the runtime. If I get the number of threads,
I need to forward declare
pthread_t mythread;
how to do that can I use pointers and use malloc()??
I also have another question. The pthread_join is used to make... (0 Replies)
I wonder if someone knows what is the rationale behind linking function calls of the POSIX threads library at link-time vs. run-time.
For example, if I create the following program:
#include <pthread.h>
void noop() {
return;
}
int main() {
pthread_self();
pthread_atfork(noop,... (1 Reply)

pthread_attr_setdetachstate
PTHREAD_ATTR_SETDETACHSTATE(3) Linux Programmer's Manual PTHREAD_ATTR_SETDETACHSTATE(3)NAME
pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get detach state attribute in thread attributes object
SYNOPSIS
#include <pthread.h>
int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);
int pthread_attr_getdetachstate(pthread_attr_t *attr, int *detachstate);
Compile and link with -pthread.
DESCRIPTION
The pthread_attr_setdetachstate() function sets the detach state attribute of the thread attributes object referred to by attr to the value
specified in detachstate. The detach state attribute determines whether a thread created using the thread attributes object attr will be
created in a joinable or a detached state.
The following values may be specified in detachstate:
PTHREAD_CREATE_DETACHED
Threads that are created using attr will be created in a detached state.
PTHREAD_CREATE_JOINABLE
Threads that are created using attr will be created in a joinable state.
The default setting of the detach state attribute in a newly initialized thread attributes object is PTHREAD_CREATE_JOINABLE.
The pthread_attr_getdetachstate() returns the detach state attribute of the thread attributes object attr in the buffer pointed to by
detachstate.
RETURN VALUE
On success, these functions return 0; on error, they return a nonzero error number.
ERRORS pthread_attr_setdetachstate(3) can fail with the following error:
EINVAL An invalid value was specified in detachstate.
CONFORMING TO
POSIX.1-2001.
NOTES
See pthread_create(3) for more details on detached and joinable threads.
A thread that is created in a joinable state should eventually either be joined using pthread_join(3) or detached using pthread_detach(3);
see pthread_create(3).
It is an error to specify the thread ID of a thread that was created in a detached state in a later call to pthread_detach(3) or
pthread_join(3).
EXAMPLE
See pthread_attr_init(3).
