  10
  11 #include <memcached.h>
  12
  13 memcached_return memcached_increment(memcached_st *ptr,
  14                                      char *key, size_t key_length,
  15                                      unsigned int offset,
  16                                      unsigned int *value);
  17 memcached_return memcached_decrement(memcached_st *ptr,
  18                                      char *key, size_t key_length,
  19                                      unsigned int offset,
  20                                      unsigned int *value);
  21 =head1 DESCRIPTION
  22
  23 memcached(1) servers have the ability to increment and decrement keys
  24 (overflow and underflow are not detected). This gives you the ability to use
  25 servers to generate sequences of values.
  26
  27 memcached_increment() takes a key and keylength and increments the value by
  28 the offset passed to it. The value is then returned via the unsigned int
  29 value pointer you pass to it.
  30
  31 memcached_decrement() takes a key and keylength and decrements the value by
  32 the offset passed to it. The value is then returned via the unsigned int
  33 value pointer you pass to it.
  34
  35 =head1 RETURN
  36
  37 memcached_increment() and memcached_decrement() return a memcached_return
  38 value. For information on this value see memcached_strerr(3).
