Pthread_create Arguments Explanation

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 t; for(t=0; t

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 pthread_create linux attributes are used. If the attributes specified by attr are modified undefined reference to `pthread_create' 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 http://stackoverflow.com/questions/7038586/return-code-from-pthread-create-is-11 if there was an implicit call to pthread_exit() using the 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 http://pubs.opengroup.org/onlinepubs/7908799/xsh/pthread_create.html exit status. The signal state of the new thread is initialised as follows: The signal 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(), . DERIVATION Derived from the POSIX Threads Extension (1003.1c-199

multi-core systems where the process flow can be scheduled to run on another processor thus gaining speed through parallel or distributed processing. Threads require less overhead than "forking" or spawning a new process because the system does not initialize a new system virtual memory space and environment for the process. While most effective on a multiprocessor system, gains are also found on uniprocessor systems which exploit latency in I/O and other system functions which may halt process execution. (One thread may execute while another is waiting for I/O or some other system latency.) Parallel programming technologies such as MPI and PVM are used in a distributed computing environment while threads are limited to a single computer system. All threads within a process share the same address space. A thread is spawned by defining a function and its arguments which will be processed in the thread. The purpose of using the POSIX thread library in your software is to execute software faster.

A thread does not maintain a list of created threads, nor does it know the thread that created it. All threads within a process share the same address space. Threads in the same process share: Process instructions Most data open files (descriptors) signals and signal handlers current working director
