NAME

       sam_data_restore - Restore previously saved user data

SYNOPSIS

       #include <corosync/sam.h>

       cs_error_t sam_data_restore (void *data, size_t size);

DESCRIPTION

       The  sam_data_restore  function  is  used  to  restore  data,  previously saved by calling
       sam_data_store(3). Such data survives between instances.

       The data parameter is pointer to memory initialized by  caller.  Stored  data  are  copied
       there. This also means, that caller is responsible for freeing memory.

       The  size parameter is length of data. This one must be at least same length as previously
       stored data otherwise error is returned. Parameter can be larger but only stored data size
       bytes are changed.

       Use sam_data_getsize(3) to find out length of stored data.

RETURN VALUE

       This call return CS_OK value if successful, otherwise and error is returned.

ERRORS

       CS_ERR_BAD_HANDLE
              component was not initialized by calling sam_initialize(3) or it was finalized.

       CS_ERR_INVALID_PARAM
              data parameter is NULL or size is less then currently stored data length
