eb_user()
Hook to the event builder task after the reception of all fragments of the same serial number. The destination event has already the final EVENT_HEADER setup with the data size set to 0. It is than possible to add private data at this point using the proper bank calls. The ebch[] array structure points to nfragment channel structure with the following content: {verbatim} typedef struct { char name[32]; // Fragment name (Buffer name). DWORD serial; // Serial fragment number. char *pfragment; // Pointer to fragment (EVENT_HEADER *) ... } EBUILDER_CHANNEL; {verbatim} The correct code for including your own MIDAS bank is shown below where { TID_xxx} is one of the valid Bank type starting with { TID_} for midas format or { xxx_BKTYPE} for Ybos data format. { bank_name} is a 4 character descriptor. { pdata} has to be declared accordingly with the bank type. Refers to the ebuser.c source code for further description. { It is not possible to mix within the same destination event different event format!} {verbatim} Event is empty, fill it with BANK_HEADER If you need to add your own bank at this stage bk_init(pevent); bk_create(pevent, bank_name, TID_xxxx, &pdata); pdata++ = ...; dest_size = bk_close(pevent, pdata); pheader->data_size = *dest_size + sizeof(EVENT_HEADER); {verbatim} For YBOS format, use the following example. {verbatim} ybk_init(pevent); ybk_create(pevent, "EBBK", I4_BKTYPE, &pdata); pdata++ = 0x12345678; pdata++ = 0x87654321; dest_size = ybk_close(pevent, pdata); dest_size *= 4; pheader->data_size = *dest_size + sizeof(YBOS_BANK_HEADER); {verbatim} Parameters nfrag Number of fragment. ebch Structure to all the fragments. pheader Destination pointer to the header. pevent Destination pointer to the bank header. dest_size Destination event size in bytes. event builder user code for private data filtering. Returns EB_SUCCESS
