SYNOPSIS
#include <corosync/cmap.h>
cs_error_t cmap_delete(cmap_handle_t handle, const char *key_name);
DESCRIPTION
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 con‐
nection to CMAP database obtained by calling cmap_initialize(3) func‐
tion. key_name is name of key to delete.
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.
