Key must be previously created by .B cmap_set(3) function. The .I handle argument is connection to CMAP database obtained by calling .B cmap_initialize(3) function. .I key_name is name of key to delete. .SH RETURN VALUE This call returns the CS_OK value if successful. If key_name is unspecified, CS_ERR_INVALID_PARAM is returned. For nonexisting keys, CS_ERR_NOT_EXIST error is returned. Some of keys may be tagged read-only directly in corosync and deleting such key will result in CS_ERR_ACCESS error. .SH "SEE ALSO" .BR cmap_initialize (3), .BR cmap_set (3), .BR cmap_overview (3)
