My problem is this:
I need to have a catch-all for my processes. An example would be, using a trap, in the parent, to catch any non-0 exit or invalid command (a way to catch core dumps would be cool, too) in not only the parent, but it's children and they're children. Not only that, but I also... (7 Replies)
I'd like to use "trap" command on my unix machine sunOS 5.7.
But somehow when I do "which trap" command, it's no where to be found.
Any one knows how I can get it installed?
Thanks!! (9 Replies)

Examples for libmemcached
DESCRIPTION
For full examples, test cases are found in tests/*.c in the main distribution. These are always up to date, and are used for each test run
of the library.
CONNECTING TO SERVERS
const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com"
memcached_st *memc= memcached(config_string, strlen(config_string);
{
...
}
memcached_free(memc);
In the above code you create a memcached_st object with three server by making use of memcached_create().
CREATING A POOL OF SERVERS
Creating a pool of Servers:
const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com";
memcached_pool_st* pool= memcached_pool(config_string, strlen(config_string));
memcached_return_t rc;
memcached_st *memc= memcached_pool_pop(pool, false, &rc);
.... do work
/*
Release the memc_ptr that was pulled from the pool
*/
memcached_pool_push(pool, memc);
/*
Destroy the pool.
*/
memcached_pool_destroy(pool);
In the above code you create a memcached_pool_st object with three server by making use of memcached_pool().
When memcached_pool_destroy() all memory will be released that is associated with the pool.
ADDING A VALUE TO THE SERVER
Adding a value to the Server:
char *key= "foo";
char *value= "value";
memcached_return_t rc= memcached_set(memc, key, strlen(key), value, value_length, (time_t)0, (uint32_t)0);
if (rc != MEMCACHED_SUCCESS)
{
... // handle failure
}
It is best practice to always look at the return value of any operation.
FETCHING MULTIPLE VALUES
memcached_return_t rc;
char *keys[]= {"fudge", "son", "food"};
size_t key_length[]= {5, 3, 4};
unsigned int x;
uint32_t flags;
char return_key[MEMCACHED_MAX_KEY];
size_t return_key_length;
char *return_value;
size_t return_value_length;
rc= memcached_mget(memc, keys, key_length, 3);
x= 0;
while ((return_value= memcached_fetch(memc, return_key, &return_key_length,
&return_value_length, &flags, &rc)))
{
free(return_value);
x++;
}
Notice that you freed values returned from memcached_fetch(). The define MEMCACHED_MAX_KEY is provided for usage.
