cmap_set - Store value in CMAP

The cmap_set function is used to store key inside cmap. The handle argument is connection to CMAP database obtained by calling cmap_initialize(3) function. key_name is name of key to set value. Key name is limited by minimal (CMAP_KEYNAME_MINLEN, currently 3) and maximal (CMAP_KEYNAME_MAXLEN, currently 255) length. Also key can contain only limited set of characters expressed by regexp [a-zA-Z0-9._-/:]*. value is pointer to allocated data which will be stored inside CMAP. Length of value (number of bytes) is supplied as value_len parameter. Last parameter is type which gives type of value. It may 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 CMAP_VALUETYPE_FLOAT - Float value CMAP_VALUETYPE_DOUBLE - Double value CMAP_VALUETYPE_STRING - C-style string CMAP_VALUETYPE_BINARY - Binary data, byte with zero value has no special meaning

cmap_set - Store value in CMAP

This call returns the CS_OK value if successful. If value or key_name are unspecified, CS_ERR_INVALID_PARAM is returned. Too short or too long key_name returns CS_ERR_NAME_TOO_LONG error code. Some of keys may be tagged read-only directly in corosync and setting such key will result in CS_ERR_ACCESS error.
