[Chicken-hackers] [PATCH] file=? function to compare two files

[Michele La Monaca]

I wasn't able to spot this kind of function in the library so I wrote it
myself. Not sure if files.scm is the right place for that. Not sure either
if inode-numbers equality in Windows is enough to state that two files are
actually the same file. Some tuning might be needed, not yet very
fluent/knowledgeable in scheme... unfortunately.


[procedure] (file=? FILE1 FILE2 #!optional FORCE-COMPARISON)


Examples:

#;1> (file=? "test_A.iso" "test_A.iso")     -->  just inode equality test
#t

#;2> (file=? "test_A.iso" "test_A.iso" #t)  -->  byte-by-byte comparison
#t


Good exercise to learn scheme. Enjoyed!
