Detailed Description

Program for developing fast compare code to run on Rad750 with data from FES.

Author:

Ed Bacho - ebacho@slac.stanford.edu

JJRussell - russell@slac.stanford.edu

Example:

    $ ebf_fes <inFileLoadedInFes.ebf> <fileFromLat.ebf>
   

For a complete explanation type ebf_fes with no arguments.

This file contains the code for a "fast" compare that will run on the Rad750. The steps are: 1) load EBF file into FES, set FES to insert fileSeqNum into GEM 2) setup LAT to collect data 3) use ebf_fes to setup this code, it will

• install a handler in LCB event to do "fast" compare
• allocate some memory to receive "bad" events
• read in the same EBF file as loaded into FES and parse it into a form to do the compare 4) startup FES 5) The installed LCB handler will do the following on each event
• use fileSeqNum stored in GEM to lookup evt data from EBF file
• start comparing received data with that stored from EBF file
• on any diff detected
  • skip rest of compares
  • save whole event to the "bad" evt memory buffer 6) WHen test completed or buffer full, one can save the "bad" events to disk with ebf_fesSave().

Note:

The host executable is for debugging this code. The 2nd file specified must be one from the FES/LAT with the fileSeqNUm embedded in the GEM header. The host prog, ebf_fes, has no use beyond this debugging.

Use ebf_diff prog should be used for comparing EBF files.

ebf_diff can also be used to analyze the "bad" file produced with program against the original EBF file.

Function Documentation

static int FillCtl	(	Ctl *	ctl,
		int	argc,
		char *const	argv[]
	)			[static]

Examines the command line parameters and fills the print control structure.

Return values:

	0,Everything	is okay.
	-1,Incorrect	command usage. Usually this means that the input file name was absent.

Parameters:

	ctl	The parameter control block.
	argc	The number of command line parameters.
	argv	The array of pointers to the command line parameters.

Host argument parsing routine

Referenced by main().

int main	(	int	argc,
		char *const	argv[]
	)

Usual entry point for the readtest.

Parameters:

	argc	The number of arguments
	argv	The vector of arguments.

Host main routine
