#Passing value in to pthread c how to#

The following piece of psuedo-code is an example of how to avoid getting a full core. This is necessary so that multi-threaded programs can be debugged with the dbx command. If a signal is received whose action is to terminate the process with a core dump, a full dump (usually much larger than a regular dump) will be produced. When a process uses the pthread_create function, and thus becomes multi-threaded, the FULL_CORE flag is enabled for all signals. This subroutine is part of the Base Operating System (BOS) Runtime. The pthread_create function will not return an error code of EINTR.

The caller does not have appropriate permission to set the required scheduling parameters or scheduling policy. 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.

The pthread_create function will fail if: EAGAIN Otherwise, an error number is returned to indicate the error. If successful, the pthread_create function returns zero. Points to the single argument to be passed to the start_routine routine. Points to the routine to be executed by the thread. If the value is NULL, the default attributes values will be used. Specifies the thread attributes object to use in creating the thread. Points to where the thread ID will be stored. This is necessary to debug multiple-threaded processes. This means that if a core file is produced, it will be much bigger than a single_threaded application. When multiple threads are created in a process, the FULL_CORE flag is set for all signals. In this case, the flag is automatically set. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. Note: The pthread.h header file must be the first included file of each source file using the threads library.

The entire process is terminated due to a call to either the exec or exit subroutines.

The thread received a signal that terminated it.

The thread called the pthread_exit subroutine.

The thread returned from its starting routine (the main routine for the initial thread).

The thread terminates in the following cases: It is not recommended to cast this pointer into a scalar data type ( int for example), because the casts may not be portable.ДЄfter thread creation, the thread attributes object can be reused to create another thread, or deleted. The arg parameter is a void pointer it can reference any kind of data. The new thread is made runnable, and will start executing the start_routine routine, with the parameter specified by the arg parameter. The new thread inherits its creating thread's signal mask but any pending signal of the creating thread will be cleared for the new thread. The pthread_create subroutine creates a new thread and initializes its attributes using the thread attributes object specified by the attr parameter.
