Pthread_threads_max

I am trying to run a simple multi threaded programming and i am getting this error from gcc return code from pthread_create() is 11 how do i solve this issue ? #include #include #include #define NUM_THREADS 20000 void *PrintHello(void *threadid) { long tid; tid = (long)threadid; printf("Hello World! It's me, thread #%ld!\n", tid); pthread_exit(NULL); } int main (int argc, char *argv[]) { pthread_t threads[NUM_THREADS]; int rc; long pthread functions t; for(t=0; t

PTHREAD_CREATE(3) NAME top pthread_create - create a new thread SYNOPSIS

Pthread_join

top #include int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine)

Pthread Mutex Example

(void *), void *arg); Compile and link with -pthread. DESCRIPTION top The pthread error handling pthread_create() function starts a new thread in the calling process. The new thread starts execution by invoking start_routine(); arg is passed as the sole argument of start_routine(). http://stackoverflow.com/questions/7038586/return-code-from-pthread-create-is-11 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 pthread_join(3). * It returns from start_routine(). This is equivalent to calling pthread_exit(3) with the value supplied in the return statement. * It http://man7.org/linux/man-pages/man3/pthread_create.3.html is canceled (see pthread_cancel(3)). * Any of the threads in the process calls exit(3), or the main thread performs a return from main(). This causes the termination of all threads in the process. The attr argument points to a pthread_attr_t structure whose contents are used at thread creation time to determine attributes for the new thread; this structure is initialized using pthread_attr_init(3) and related functions. If attr is NULL, then the thread is created with default attributes. Before returning, a successful call to pthread_create() stores the ID of the new thread in the buffer pointed to by thread; this identifier is used to refer to the thread in subsequent calls to other pthreads functions. The new thread inherits a copy of the creating thread's signal mask (pthread_sigmask(3)). The set of pending signals for the new thread is empty (sigpending(2)). The new thread does not inherit the creating thread's alternate signal stack (sigaltstack(2)). The new thread inherits the calling th

void *(*start_routine)(void*), void *arg); DESCRIPTION The pthread_create() function is used to create a new thread, with attributes specified by attr, within a process. If attr is NULL, the default attributes are used. If the http://pubs.opengroup.org/onlinepubs/7908799/xsh/pthread_create.html attributes specified by attr are modified later, the thread's attributes are not affected. Upon successful completion, pthread_create() stores the ID of the created thread in the location referenced by thread. The thread is created executing start_routine with arg as its sole argument. If the start_routine returns, the effect is as if there was an implicit call to pthread_exit() using the pthread error return value of start_routine as the exit status. Note that the thread in which main() was originally invoked differs from this. When it returns from main(), the effect is as if there was an implicit call to exit() using the return value of main() as the exit status. The signal state of the new thread is initialised as follows: The signal pthread_create example c mask is inherited from the creating thread. The set of signals pending for the new thread is empty. If pthread_create() fails, no new thread is created and the contents of the location referenced by thread are undefined. RETURN VALUE If successful, the pthread_create() function returns zero. Otherwise, an error number is returned to indicate the error. ERRORS The pthread_create() function will fail if: [EAGAIN] The system lacked the necessary resources to create another thread, or the system-imposed limit on the total number of threads in a process PTHREAD_THREADS_MAX would be exceeded. [EINVAL] The value specified by attr is invalid. [EPERM] The caller does not have appropriate permission to set the required scheduling parameters or scheduling policy. The pthread_create() function will not return an error code of [EINTR]. EXAMPLES None. APPLICATION USAGE None. FUTURE DIRECTIONS None. SEE ALSO pthread_exit(), pthread_join(), fork(), .
