Function Documentation

switch_status_t switch_thread_create (  switch_thread_t **  new_thread, switch_threadattr_t *  attr, switch_thread_start_t  func, void *  data, switch_memory_pool_t *  cont )

Create a new thread of execution Parameters: new_thread  The newly created thread handle. attr  The threadattr to use to determine how to create the thread func  The function to start the new thread in data  Any data to be passed to the starting function cont  The pool to use { return apr_thread_create(new_thread, attr, func, data, cont); }

switch_status_t switch_threadattr_create (  switch_threadattr_t **  new_attr, switch_memory_pool_t *  pool )

Create and initialize a new threadattr variable Parameters: new_attr  The newly created threadattr. pool  The pool to use { return apr_threadattr_create(new_attr, pool); }

switch_status_t switch_threadattr_detach_set (  switch_threadattr_t *  attr, int32_t  on )

Set if newly created threads should be created in detached state. Parameters: attr  The threadattr to affect on  Non-zero if detached threads should be created. { return apr_threadattr_detach_set(attr, on); }

switch_status_t switch_threadattr_priority_increase (  switch_threadattr_t *  attr  )

{ int stat = 0; #ifndef WIN32 struct sched_param param; struct apr_threadattr_t *myattr = attr; pthread_attr_getschedparam(&myattr->attr, &param); param.sched_priority = 50; stat = pthread_attr_setschedparam(&myattr->attr, &param); if (stat == 0) { return SWITCH_STATUS_SUCCESS; } #endif return stat; }

switch_status_t switch_threadattr_stacksize_set (  switch_threadattr_t *  attr, switch_size_t  stacksize )

{ return apr_threadattr_stacksize_set(attr, stacksize); }
