这个是最基本的。:slight_smile:

#include <stdio.h>
#include <sys/iofunc.h>
#include <sys/dispatch.h>
#include <sys/neutrino.h>
#include <sys/resmgr.h>

dispatch_t *dpp;
int res_id;

int main()
{
    thread_pool_attr_t pool_attr;
    thread_pool_t *tpp;

    resmgr_attr_t res_attr;
    resmgr_io_funcs_t io_funcs;
    resmgr_connect_funcs_t cf;
    iofunc_attr_t attr;

    memset(&pool_attr, 0, sizeof pool_attr);
    if ((pool_attr.handle = dpp = dispatch_create()) == NULL) {
        perror("dispatch_create");
        return -1;
    }
    pool_attr.context_alloc = (void *)dispatch_context_alloc;
    pool_attr.block_func = (void *)dispatch_block;
    pool_attr.handler_func = (void *)dispatch_handler;
    pool_attr.context_free = (void *)dispatch_context_free;
    pool_attr.lo_water = 2;
    pool_attr.hi_water = 3;
    pool_attr.increment = 1;
    pool_attr.maximum = 5;
    if(!(tpp = thread_pool_create(&pool_attr, POOL_FLAG_EXIT_SELF))) {
        perror("thread_pool_create");
        return -1;
    }

    memset(&res_attr, 0x00, sizeof res_attr);
    res_attr.nparts_max = 10;

    iofunc_attr_init(&attr, S_IFNAM | 0666, 0, 0);
    iofunc_func_init(_RESMGR_CONNECT_NFUNCS, &cf,
                            _RESMGR_IO_NFUNCS, &io_funcs);

    if((res_id = resmgr_attach(dpp, &res_attr, "/dev/mymgr",
            _FTYPE_ANY, 0, &cf, &io_funcs, &attr)) == -1) {
        perror("resmgr_attach(/dev/mymgr)");
        return -1;
    }

    return thread_pool_start(tpp);
}
