Examples:

#include <sys/dispatch.h>
#include <stdio.h>
#include <stdlib.h>

int main( int argc, char **argv ) {
   thread_pool_attr_t   pool_attr;
   thread_pool_t        *tpp;
   dispatch_t           *dpp;
   resmgr_attr_t        attr;
   resmgr_context_t     *ctp;

   if( (dpp = dispatch_create()) == NULL ) {
     fprintf( stderr, "%s: Unable to allocate \
              dispatch context.\n", argv[0] );
     return EXIT_FAILURE;
   }

   memset( &pool_attr, 0, sizeof (pool_attr) );
   pool_attr.handle = dpp; 
   pool_attr.context_alloc = dispatch_context_alloc; 
   pool_attr.block_func = dispatch_block; 
   pool_attr.unblock_func = dispatch_unblock; 
   pool_attr.handler_func = dispatch_handler; 
   pool_attr.context_free = dispatch_context_free;
   pool_attr.lo_water = 2;
   pool_attr.hi_water = 4;
   pool_attr.increment = 1;
   pool_attr.maximum = 50;

   if( (tpp = thread_pool_create( &pool_attr,
              POOL_FLAG_EXIT_SELF )) == NULL ) {
     fprintf( stderr, "%s: Unable to initialize \
              thread pool.\n", argv[0] );
     return EXIT_FAILURE;
   }

   …

   /* Never returns */
   thread_pool_start( tpp );
