Asked by Panin Sergey

Simple project:

#include <string.h>
#include <libmemcached/memcached.h>

int main( void )
{
 return 0;
}

Compile line:
g++ -Wall -o mc mc.cpp -lmemcached -I/usr/include/libmemcached/

Example 2

#include <libmemcached/memcached.h>
#include <string.h>
#include <cstring>

int main( void )
{
 char *key = "key";
 char *value = "value";
 uint32_t flags = 0;
 size_t length = 0;
 char *value2 = NULL;
 memcached_return rc;

 memcached_st *memc = memcached_create(NULL);
 memcached_server_add(memc,"localhost",11211);
 rc = memcached_set(memc, key, strlen(key), value, strlen(value)+1, (time_t)0, flags);
 memcached_free(memc);
 return 0;
