Pthreads Error Code 11
Indeed, a thread could execute a function that modifies errno just before you check the value in another thread. The new thread terminates in one of the following ways: * It calls pthread_exit(3), specifying an exit status value that is available to another thread in the same process that calls This causes the termination of all threads in the process. My guess was in some case, without time delay, pthread_detach() may be called even before the thread has been initialized. http://vealcine.com/error-code/r6-error-code-11.php
Using pthread_attr_setstacksize(3), the stack size attribute can be explicitly set in the attr argument used to create a thread, in order to obtain a stack size other than the default. The latest is PHCO_36323 and the recommended one is PHCO_35997. 0 Kudos Reply The opinions expressed above are the personal opinions of the authors, not of Hewlett Packard Enterprise. In order to enable backwards compatibility so that multithreaded pages can run in non-supporting browsers (except with pthread_create() disabled), pass the linker flag -s USE_PTHREADS=2 instead. See bug 3495 for more information and how to work around this until proxying is no longer needed in Emscripten. http://stackoverflow.com/questions/7038586/return-code-from-pthread-create-is-11
How To Find Pthread_threads_max
Then tuned kernel to max_thread_proc=512, still the problem remains.note that I could run the programs 32-bit version on same machine without any problem but the 64-bit version shows the problem.please let lordslimey posted Oct 3, 2016 How to remove an empty line which is created when i deleted a element from my xml file? Differentiation of sine in Fourier domain What stops messenger RNA from binding to itself? EAGAIN A system-imposed limit on the number of threads was encountered.
- If a thread is joinable, then another thread can call pthread_join(3) to wait for the thread to terminate and fetch its exit status.
- On my system, errno.h says: #define EDEADLK 11 /* Resource deadlock avoided */ /* 11 was EAGAIN */ So, 11 once was EAGAIN, which is a known return for pthread_create().

The return value of emscripten_has_threading_support() denotes whether the browser has shared memory support available. But most of what I can say about pthreads is guesses.

How To Find Pthread_threads_max Since my proposal was going to be viewed by many Austin Group's contributors (some being "recognized UNIX authority"), I tried to make my example as perfect as possible. Pthread Error Codes To String in a CDN environment, then one can define the Module.locateFile(filename) function in the main HTML Module object to return the URL of the target location of the pthread-main.js entry point.
On my system, errno.h says: > #define EDEADLK 11 /* Resource deadlock avoided */ > /* 11 was EAGAIN */ > > So, 11 once was EAGAIN, which is a known this contact form Bugs can be reported to the Emscripten bug tracker as usual. By default, pthread-main.js will be loaded relative to the main HTML page URL. Where is the code for the "Proceed To Checkout" located? Error Return Code From Pthread_create Is 11 Error Detail Resource Temporarily Unavailable
I can easily start 30000 threads with a stack size of 8MB. Pthread_create Resource Temporarily Unavailable However, unless this is just a trivial example for toying around (or maybe even then) you might want to look into the concept of thread pools and queues. Butenhof: Programming with POSIX Threads, chap 1.9.3, pp 31-34, Addison-Wesley, ISBN 0-201-63392-2.
In order to keep proxying as responsive as possible, whenever main thread calls to a function that performs a futex wait, e.g.
Multiple password fields for one login Was Sigmund Freud "deathly afraid" of the number 62? Only when a terminated joinable thread has been joined are the last of its resources released back to the system. Drew Lawson Guest In article <> Harshith <> writes: [First, I agree with asking the next question in the threading group.] >i have a code that uses pthread, but when i Pthread_attr_setstacksize It seems likely that it is, given the code that produced it.
NOTES top See pthread_self(3) for further information on the thread ID returned in *thread by pthread_create(). This is because it is not possible to send signals to web workers and pre-empt their execution. We are using gcc on intel, when i compile 32 bit I have to use -m32 -march=i686. -march is needed when using the atomic builtins. Check This Out How do I link against system libraries like SDL, boost, etc.?
This proxying can generate a deadlock in a special situation that native code running pthreads does not have. Subsequent calls to pthread_mutex_lock() will behave normally. Porting Code Portability and Limitations Portability Guidelines Code that cannot be compiled Code that compiles but might run slowly API Limitations Networking File Systems Application Main Loop Other APIs Function Pointer pthread_create hangs.
Antoninus Twink, May 28, 2009 #2 Advertisements Show Ignored Content Want to reply to this thread or ask your own question? Why do I get undefined is not a function or NAME is not a function? Note that the maximum number of threads that can be created depends on your system (and possibly even depends on a number of other settings). The code snippet below underlines the difference between the errno and the Pthreads way of reporting errors: #include

You'll be able to ask questions about coding or chat with the community and help others. The program is 64-bit.
If it is desirable to load the file from a different location e.g. If -1 is passed to both PTHREAD_POOL_SIZE and PTHREAD_HINT_NUM_CORES, then a popup dialog will ask the user the size of the pool (useful for testing). strerror() will print the error code by the way. Please check these first in case of any issues.
