cmap_delete(3) Delete key/value pair from the CMAP service


#include <corosync/cmap.h>

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


The cmap_delete function is used to delete key from cmap. Key must be previously created by cmap_set(3) function. The handle argument is connection to CMAP database obtained by calling cmap_initialize(3) function. key_name is name of key to delete.


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.
