* Function: main

* Purpose: h5diff main program
|
|
*
|
|
* Return: An exit status of 0 means no differences were found, 1 means some
|
|
* differences were found.

* Modifications: July 2004
|
|
* Introduced the four modes:
|
|
* Normal mode: print the number of differences found and where they occured
|
|
* Report mode: print the above plus the differences
|
|
* Verbose mode: print the above plus a list of objects and warnings
|
|
* Quiet mode: do not print output
|
|
*
|
|
* November 2004: Leon Arber (larber@uiuc.edu)
|
|
* Additions that allow h5diff to be run in parallel
|
|
*
|
|
* February 2005: Leon Arber (larber@uiuc.edu)
|
|
* h5diff and ph5diff split into two files, one that is used
|
|
* to build a serial h5diff and one used to build a parallel h5diff
|
|
* Common functions have been moved to h5diff_common.c
|
|
*
|
|
* October 2005
|
|
* Introduced a new field 'not_cmp' to 'diff_opt_t' that detects
|
|
* if some objects are not comparable and prints the message
|
|
* "Some objects are not comparable"
|
|
*
|
|
* February 2007
|
|
* Added comparison for dataset regions.
|
|
* Added support for reading and comparing by hyperslabs for large files.
|
|
* Inclusion of a relative error formula to compare floating
|
|
* point numbers in order to deal with floating point uncertainty.
|
|
* Printing of dataset dimensions along with dataset name
|
|
*
|
|
* November 19, 2007
|
|
* adopted the syntax h5diff [OPTIONS] file1 file2 [obj1[obj2]]
