       cmap_inc - Increase already stored value in CMAP

       #include <corosync/cmap.h>

       cs_error_t cmap_inc (cmap_handle_t handle, const char *key_name);

       The  cmap_inc  function	is  used  to increase integer value of already
       stored key inside cmap. The handle argument is connection to CMAP data‐
       base obtained by calling cmap_initialize(3) function.  key_name is name
       of key to increase value of.

       Function is defined only on values where increase makes	sense  and  is
       well defined, so it can be one of:

       CMAP_VALUETYPE_INT8 - 8-bit signed interger

       CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer

       CMAP_VALUETYPE_INT16 - 16-bit signed interger

       CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer

       CMAP_VALUETYPE_INT32 - 32-bit signed interger

       CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer

       CMAP_VALUETYPE_INT64 - 64-bit signed interger

       CMAP_VALUETYPE_UINT64 - 64-bit unsigned integer

       Overflow/underflow is not detected and it's ignored.

       This  call  returns the CS_OK value if successful. If value or key_name
       are unspecified,	 CS_ERR_INVALID_PARAM  is  returned.  CS_ERR_NOT_EXIST
       error  is  returned  if	key  doesn't  exist (wasn't created by calling
       cmap_set(3) first). Some of keys may be tagged  read-only  directly  in
       corosync and seting such key will result in CS_ERR_ACCESS error.

       CS_ERR_NOT_SUPPORTED The requested protocol/functuality not supported
