kupl_queue_wait_all

Synchronize all queues created by calling the kupl_queue_acquire interface.

Interface Definition

int kupl_queue_wait_all();

Parameters

None

Return Value

Success: KUPL_OK

Failure: KUPL_ERROR

Examples

#include <stdio.h> 
#include "kupl.h" 

static inline void kernel_func(void *args)
{
    printf("kernel exec.\n");
}

int main() 
{ 
    kupl_queue_h q1 = kupl_queue_acquire(1); 
    kupl_queue_h q2 = kupl_queue_acquire(2); 
    kupl_queue_item_desc_t desc = {
        .field_mask = KUPL_QUEUE_ITEM_DESC_FIELD_NAME,
        .func = kernel_func,
        .args = NULL,
        .name = "kernel_name"
    };
    kupl_queue_submit(q1, &desc); 
    kupl_queue_submit(q2, &desc); 
    kupl_queue_wait_all(); 
    return 0; 
}

The preceding example demonstrates how to obtain the handles of queues numbered 1 and 2, submit an item to each queue, and then use kupl_queue_wait_all for synchronization.
