17 The cmap_delete function is used to delete key from cmap. Key must be
18 previously created by cmap_set(3) function. The handle argument is con‐
19 nection to CMAP database obtained by calling cmap_initialize(3) func‐
20 tion. key_name is name of key to delete.

24 This call returns the CS_OK value if successful. If key_name is unspec‐
25 ified, CS_ERR_INVALID_PARAM is returned. For nonexisting keys,
26 CS_ERR_NOT_EXIST error is returned. Some of keys may be tagged read-
27 only directly in corosync and deleting such key will result in
28 CS_ERR_ACCESS error.
