NAME¶
memcached_create - libmemcached Documentation
SYNOPSIS¶
- #include <libmemcached/memcached.h>
- Compile and link with -lmemcached
- Parameters
- ptr -- pointer to user-allocated memcached_st struct or null pointer
- Returns
- pointer to initialized memcached_st struct
- Parameters
- ptr -- pointer to initialized memcached_st struct to destroy and possibly free
- destination -- pointer to user-allocated memcached_st struct or null pointer
- source -- pointer to initialized memcached_st struct to copy from
- Returns
- pointer to newly initialized destination, copied from source
- Parameters
- ptr -- pointer to initialized memcached_st struct
DESCRIPTION¶
memcached_create() is used to create a memcached_st structure that will then be used by other libmemcached functions to communicate with the server. You should either pass a statically declared memcached_st to memcached_create() or a NULL. If a NULL passed in then a structure is allocated for you.
Please note, when you write new application use memcached() over memcached_create().
memcached_clone() is similar to memcached_create() but it copies the defaults and list of servers from the source memcached_st pointer. If you pass a null as the argument for the source to clone, it is the same as a call to memcached_create(). If the destination argument is NULL a memcached_st will be allocated for you.
memcached_servers_reset() allows you to zero out the list of servers that the memcached_st has.
To clean up memory associated with a memcached_st structure you should pass it to memcached_free() when you are finished using it. memcached_free() is the only way to make sure all memory is deallocated when you finish using the structure.
You may wish to avoid using memcached_create() or memcached_clone() with a stack based allocation. The most common issues related to ABI safety involve heap allocated structures.
RETURN VALUE¶
memcached_create() returns a pointer to the memcached_st that was created (or initialized). On an allocation failure, it returns NULL.
memcached_clone() returns a pointer to the memcached_st that was created (or initialized). On an allocation failure, it returns NULL.
