NAME

       sam_data_store - Store user data

SYNOPSIS

       #include <corosync/sam.h>

       cs_error_t sam_data_store (const void *data, size_t size);

DESCRIPTION

       The sam_data_store function is used to store data, which survives between instances.

       The  data  parameter  is  pointer  to  memory with data to store. Data are stored in newly
       allocated memory inside library, so caller can safely remove them after call of function.

       You can use NULL as parameter to remove and free previously saved data. In this case  size
       argument is ignored.

       The size parameter is length of data.

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

RETURN VALUE

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

ERRORS

       CS_ERR_BAD_HANDLE
