CMAP_INC(3)	  Corosync Cluster Engine Programmer's Manual	   CMAP_INC(3)

NAME
       cmap_inc	- Increase already stored value	in CMAP

SYNOPSIS
       #include	<corosync/cmap.h>

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

DESCRIPTION
       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 integer

       CMAP_VALUETYPE_UINT8 - 8-bit unsigned integer

       CMAP_VALUETYPE_INT16 - 16-bit signed integer

       CMAP_VALUETYPE_UINT16 - 16-bit unsigned integer

       CMAP_VALUETYPE_INT32 - 32-bit signed integer

       CMAP_VALUETYPE_UINT32 - 32-bit unsigned integer

       CMAP_VALUETYPE_INT64 - 64-bit signed integer

       CMAP_VALUETYPE_UINT64 - 64-bit unsigned integer

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

RETURN VALUE
       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 er-
       ror  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 setting such key will result in CS_ERR_ACCESS error.

       CS_ERR_INTERRUPT	System call interrupted	by a signal

       CS_ERR_NOT_SUPPORTED The	requested protocol/functionality not supported
