cmap_get – Retrieve value from CMAP Synopsis#include <corosync/cmap.h> cs_error_t cmap_get (cmap_handle_t handle, const char *key_name, void *value, size_t *value_len, cmap_value_types_t *type); Also shortcuts for different types are defined cs_error_t cmap_get_int8 (cmap_handle_t handle, const char *key_name, int8_t *i8); cs_error_t cmap_get_uint8 (cmap_handle_t handle, const char *key_name, uint8_t *u8); cs_error_t cmap_get_int16 (cmap_handle_t handle, const char *key_name, int16_t *i16);…

cmap_finalize – Finalize connection to CMAP Synopsis#include <corosync/cmap.h> cs_error_t cmap_finalize (cmap_handle_t handle); DescriptionThe cmap_finalize function is used to to close a connection to the CMAP API. Once the connection is finalized, the handle may not be used again by applications. No more callbacks will be dispatched from the cmap_dispatch function. Return ValueThis call returns the…

cmap_fd_get – Dispatches callbacks from the CMAP service Synopsis#include <corosync/cmap.h> cs_error_t cmap_fd_get (cmap_handle_t handle, int *fd); DescriptionThe cmap_fd_get function is used to retrieve the file descriptor that may be used with the poll system call to determine when cmap_dispatch(3) won’t block. The handle argument may not be used directly with poll because it is not…

cmap_dispatch – Dispatches callbacks from the CMAP service Synopsis#include <corosync/cmap.h> cs_error_t cmap_dispatch (cmap_handle_t handle, cs_dispatch_flags_t dispatch_types); DescriptionThe cmap_dispatch function is used to dispatch configuration changes. Each application may have several connections to the CMAP API. Each application uses the handle argument to uniquely identify the connection. The dispatch_types argument is used to identify the type…

cmap_delete – Delete key/value pair from the CMAP service Synopsis#include <corosync/cmap.h> cs_error_t cmap_delete(cmap_handle_t handle, const char *key_name); DescriptionThe 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….

cmap_inc – Decrease already stored value in CMAP Synopsis#include <corosync/cmap.h> cs_error_t cmap_dec (cmap_handle_t handle, const char *key_name); DescriptionThe cmap_dec function is used to decrease integer value of already stored 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 increase value of. Function…

cmap_context_set – Sets the context variable for a CMAP instance Synopsis#include <corosync/cmap.h> cs_error_t cmap_context_set (cmap_handle_t handle, const void *context); DescriptionThe cmap_context_set function is used to store the context variable for cmap instance. It has no meaning insire libcmap itself and will not be touched by the library. It can be retrieved using cmap_context_get(3). Return ValueThis…

cmap_context_get – Gets the context variable for a CMAP instance Synopsis#include <corosync/cmap.h> cs_error_t cmap_context_get (cmap_handle_t handle, const void **context); DescriptionThe cmap_context_get function is used to retrieve the context variable previously stored using cmap_context_set(3). Return ValueThis call returns the CS_OK value if successful, otherwise an error is returned. See Alsocmap_context_set(3), cmap_overview(8) CS_ERR_TRY_AGAIN Resource temporarily unavailable CS_ERR_INVALID_PARAM…
