Re: something.tex changed on disk; really edit the buffer?

[agjf . tucker]

I have searched the archives, where I found this advice to someone suffering a 
similar problem:

"To find out what's going on, invoke the function visited-file-modtime from the 
buffer of the offending file, and compare the result it returns with the time 
stamp for that file returned by file-attributes."

I have tried running these functions with M-x but I get [No Match].  Any ideas?
