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

NAME
cpg_local_get - Returns the local node id SYNOPSIS
#include <corosync/cpg.h> int cpg_local_get(cpg_handle_t handle, unsigned int *local_nodeid); DESCRIPTION
The cpg_local_get function is used to determine the local node's identifier. The argument handle is used to reference the cpg instantia- tion. The argument local_nodeid will return the 32 bit node id. ERRORS
The errors are undocumented. SEE ALSO

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

NAME
cpg_mcast_joined - Multicasts a zero copy buffer to all groups joined to a handle SYNOPSIS
#include <sys/uio.h> #include <corosync/cpg.h> int cpg_zcb_mcast_joined(cpg_handle_t handle, cpg_guarantee_t guarantee, const void *buffer,int msg_len ); DESCRIPTION
The cpg_zcb_mcast_joined function will multicast a zero copy buffer message to all the processes that have been joined with the cpg_join(3) funtion for the same group name. Messages that are sent to any of the groups joined to the parameter handle will be delivered to all sub- scribed processes in the system. The argument guarantee requests a delivery guarantee for the message to be sent. The cpg_guarantee_t type is defined by: typedef enum { CPG_TYPE_UNORDERED, /* not implemented */ CPG_TYPE_FIFO, /* same as agreed */ CPG_TYPE_AGREED, /* implemented */ CPG_TYPE_SAFE /* not implemented */ } cpg_guarantee_t; The meanings of the cpg_guarantee_t typedef are: CPG_TYPE_UNORDERED Messages are guaranteed to be delivered, but with no particular order. This mode is unimplemented in the CPG library. CPG_TYPE_FIFO Messages are guaranteed to be delivered in first sent first delivery order. In fact, this guarantee is equivalent to the CPG_TYPE_AGREED guarantee. CPG_TYPE_AGREED All processors must agree on the order of delivery. If a message is sent from two or more processes at about the same time, the delivery will occur in the same order to all processes. CPG_TYPE_SAFE All processes must agree on the order of delivery. Further all processes must have a copy of the message before any delivery takes place. This mode is unimplemented in the CPG library. The msg argument describes the zero copy buffer which is used to transmit a message. this buffer must be allocated by cpg_zcb_alloc(3). The msg_len argument describes the number of bytes to be transmitted in the zero copy buffer. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO
