CMAP_INITIALIZE_MAP(3) Corosync Cluster Engine Programmer's Manual CMAP_INITIALIZE_MAP(3)


cmap_initialize_map - Initialize CMAP API with a specific map


#include <corosync/cmap.h>

cs_error_t cmap_initialize_map (cmap_handle_t *handle, cmap_map_t map);


The cmap_initialize_map function is used to initialize a connection to the Configuration Map API and specify a particular map to use. Each application may have several connections to the CMAP API and to different maps. Each application uses the handle argument to uniquely identify the connection. The handle argument is then used in other function calls to identify the connection to be used for communication with the CMAP service.

The map argument specifies which map to connect to. CMAP_MAP_ICMAP is the configuration map that contains the current corosyn cconfiguraton and some runtime variables that maybe useful to external agents. CMAP_MAP_STATS is the statistics map that contains detailed information about network and inter-process communications.


This call returns the CS_OK value if successful, otherwise an error is returned.
